Automated and Electric Vehicles Bill (Second sitting)

Oliver Letwin Excerpts

Committee Debate: 2nd sitting: House of Commons
Tuesday 31st October 2017 Public Bill Committees

[Mr Hayes]

How very interesting.

David Wong: That is an empirical study.

[Sir Oliver Letwin (West Dorset) (Con)]

Q We heard earlier from the insurance industry that they had been led to believe that autonomous vehicles, as they evolved and eventually came to market, would inevitably contain software that would enable the vehicle to reject a transfer from the driver to the autonomous system if it was in a location that made it unsafe for the autonomous system to operate. I am talking about the period during which we do not have cars without any steering wheels but we have ones that are sometimes autonomous and sometimes used by drivers. Do you share their confidence that vehicles will always be manufactured with software that prevents handover to the autonomous system except where it is totally safe?

David Wong: I think it is more likely to be the other way around. That is, it will be a question not of whether the system rejects a request from the driver to hand control over to the vehicle, but of whether the system serves up the offer of automation to the driver, given the right and safe conditions.

[Sir Oliver Letwin]

Q Does that mean that if the system does not make the offer, the driver will not be able to give it control?

David Wong: Correct, and I can give you an example. It is not autonomous yet, but it is level 3, which is very close to autonomous; this is the next step towards autonomy. Audi is the first vehicle manufacturer in the world to launch a level 3-capable vehicle. It launched it in the summer, and it will be available on the market, all being well, next year. Its system, which is called traffic jam pilot, is designed to operate at speeds of no more than 38 mph, on dual carriageways with clearly marked road signs as well as lane markings, and where the vehicle is hemmed in by other vehicles on the left and right, and front and back. If the system detects that all those conditions are met and the weather is sufficiently good for the operation of traffic jam pilot, it will offer the driver the option of giving the system control during that use case. Once one of those conditions is no longer in place, no longer valid—perhaps traffic has dispersed and the vehicle is able to travel at more than 38 mph—then the vehicle will ask the driver to take back control. So it is the system that will detect and serve up the offer; it is not the driver requesting.

[Sir Oliver Letwin]

Q Thank you. A question about charging points, which you were talking about: how important do you think it is that there should be a charging point in every place where there is a lawful parking space by a pavement in a city or town? What kind of timescale would you envisage for needing that level of penetration?

Steve Gooding: I doubt whether we would need precisely that level of penetration. A report that we recently published—and thinking about how the Bill’s powers might be used if the House grants them—draws out the important point which is to think about the sort of trips that people actually make. For example, in large parts of London, in residential areas where there is no off-street parking, if we are to see a wide-scale move to plug-in electric vehicles, we would need to see quite a lot of roadside recharging capacity, because lots of people would be charging overnight, because that is what is most convenient for them. Elsewhere, if people are charging overnight at their homes and perhaps looking to top up the charge at their destination, it is probably more likely that that destination might be their place of work where there is off-street parking, or it might be a shopping centre or a multi-storey car park. So we are probably not talking about universal coverage but certainly more than we have today.

Quite how fast that needs to happen, I am afraid I could not give you a figure for now. All I can say is that at the moment there are various figures. Research by Addison Lee, for example, suggests that a very intense increase in on-street presence would be needed if we were to have the sort of ramp-up of vehicles that it would be willing to engage in. I would probably focus on making sure that the grant scheme for home charging carries on, so that we encourage more people to have the facility to charge at home. Then I would probably focus on motorway service areas, which will be very important for short and rapid top-up for people making a longer journey but who are possibly anxious about managing the whole journey there and back.

David Wong: If I can quickly echo what Steve said, it is no longer about the number of charge points, because we have around 14,000 in the UK at the moment, which is one of the highest numbers in Europe, if not the highest; it is about where these charge points are—being in the right place to serve particular needs, so it is not every charge point in every corner of a neighbourhood. First and foremost, what the Bill will provide is actually a step in the right direction, and so this is something we totally support in terms of the infrastructure. This calls for a co-ordinated approach involving the Government, the SMMT, the industry, vehicle manufacturers, charge point operators, energy companies and local authorities to come together, convened by Government of course, using the Government’s convening power, to determine and plot where the right charge points ought to be, depending on usage, the likely needs of people to charge and the type of charge points, because they might be fast chargers—rapid chargers—as Steve hinted.

[Sir Oliver Letwin]

Q Do you think that there needs to be, in effect, a national plan for the location of the charge points as we approach 2040?

David Wong: We would suggest a nationally co-ordinated approach.

Brian Madderson: I speak for 75% of the motorway service areas and the one thing that they are really against is any form of mandating, because they want the market to be able to choose what is the best form of charging at the time for them. This is in a great state of flux. Some of them have already entered into agreements that are more binding than perhaps they would have wished with the knowledge that they have just 12 months on. The mandating process seems to be all stick and no carrot. These motorway service areas fully recognise the need and, in fact, many now have both Tesla charging and other forms of charging, so they are working towards that but they think mandating is not appropriate in this case.

One of the other issues the motorway service areas have is that there does not seem to be joined-up government, which I think David was probably referring to. There are planning difficulties in getting car park extensions to put in extra parking bays for Tesla charging, for example. One of the things the Government should perhaps be mandating is not where the charging points go, but that where there are planning applications for charging points, local authorities must deal with them quickly, efficiently and sympathetically.

[Clive Efford (Eltham) (Lab)]

Q What is the incentive to develop the automated car technology? Is it large fleet owners who employ a lot of drivers wanting to cut down on their overhead staff costs? Or is it the private car industry?

Steve Gooding: From a consumer perspective, I would have to say that we do not really know yet, but there is a broad spectrum of what might happen next. For example, there is a clear incentive for a fleet operator who is counting every penny to be thinking, “How could I reduce my costs of operation?” Whether that is a fleet of vans or trucks, the operator would be looking at automation as a way of, first, saving money, and secondly, sweating the asset of that truck for longer hours. In turn, we are seeing a huge amount of investment in the auto sector in vehicles for the private market.

If I were to bet my money, I would say that the guys who are counting every penny will probably be the first in—people running fleets and large numbers of vehicles—but some people are clearly very attracted to the thought of having driverless capability. That could be from time to time, or it could mean freedom and independence for people who are currently denied that by the fact that they cannot drive, and we have just been engaged in a report on what it means for people with disabilities.

[Matt Western (Warwick and Leamington) (Lab)]

Q I was interested in Mr Madderson’s point about not mandating. The car industry has often reacted well when it has been mandated to do things; when things such as Euro NCAP were introduced, it followed suit and made dramatic improvements. Given the ambition of the Government and across all parties to see more adoption of ultra low emission vehicles, and given that markets such as Norway’s are much further ahead than ours, what should we be doing to ensure that we are in a leadership position in electric vehicle technology?

Brian Madderson: It is also about providing the carrot by way of funding. That is going to be the big spur to encourage firms, in a rapidly changing market, to take that investment decision and to ensure that such decisions are supported by their banks, lenders, shareholders and others. At the moment, you do not appear to be mandating hotels, leisure centres or workplaces, all of which are admirably fine locations for charging points; you just seem to be mandating motorway service areas and large fuel retailers, whatever that description means. We do not think that is fair, reasonable or necessary.

[Sir Oliver Letwin]

Q I just want to clarify something that Steve Gooding said. Why do you think that it is clear that clause 2(1), which refers to

“an automated vehicle when driving itself”,

applies only to level 4? Why does it not apply to level 3?

Steve Gooding: I am not a parliamentary draftsman, so I would have to be reassured about this, but to me “when driving itself” means that the driver of the vehicle is not legally responsible for the vehicle; the vehicle is driving itself. That is what I intended to convey.

[Karl Turner]

Q On charging infrastructure, we have just heard evidence from the Petrol Retailers Association, which is very worried about being mandated to have charging points on the forecourts of its members. What is your prediction of what would happen if we did not mandate them to do that? If it was not required by law physically to invest and have them on their forecourts, would they bother?

Marcus Stewart: At the moment, the majority of people who own electric vehicles charge them at home, but there is a limit to how many houses have off-street parking. About 43% of properties do not have access to off-street parking, therefore other forms of charging facilities need to be available. They could be a mixture of charging types at destinations, workplaces, supermarkets, and so on.

From the evidence that we have gathered when we have talked to and interviewed people, key locations on the motorway and strategic network are seen as key enablers for the roll-out of electric vehicles and will help to remove some of the concerns around range anxiety which is seen as one of the main barriers to the take-up of electric vehicles at the moment. Charging and plus charging in particular at key locations across the country will facilitate the roll-out. If you do not have that, it is likely that the roll-out will be slower.

Suleman Alli: I support that. I would say that there is going to be a paradigm shift. It is a bit like when we used to get water from a well and we now get it from a tap in our home. In the same way, I do not think that petrol forecourts will be the only place where we will recharge our vehicles in the future. In our engagement with the marketplace, we are seeing major supermarkets looking at how they can offer fast charging to be a key differentiator for their customers. We are seeing hotels considering the same and local authorities looking to explore how on-street charging can be part of the solution. Based on the engagement we have done, I believe that it will be a much more diversified charging environment: it will not just be petrol forecourts.

Robert Evans: We have members who are very interested to install charge points at these locations. They see them as locations where there will be high utilisation rate and a good economic case for those charge points to be used. We are also talking here about an insurance policy—it is not a mandating per se. If the market does not deliver, the Act gives Government the ability to step in. It is not by definition a mandating until you pass additional legislation.

The members are very interested in installing in these locations, but they are other people’s land. Part of the issue here is the ability to encourage landowners to install charge points at their locations. In some cases it is a fuel supplier, in other cases it is one of the three main companies that operate motorway service areas. You have to recognise that there is a desire to install in those locations, but you cannot put your asset on someone else’s land.

[Sir Oliver Letwin]

Q I am delighted to hear what you say and absolutely agree with you. If the problem of range anxiety is addressed or partially addressed by fast charging at service stations and so on, we are still left with—I think you said—40% of homes that do not have off-street car parking. Have you done any assessment of the kinds of costs involved for the distribution network operators if over the period between now and 2040 there was a roll-out of universal charge points on the street in towns and cities—probably not all areas—where there is lawful parking?

--- Later in debate ---

[The Chair]

We are now quorate. Sir Oliver Letwin asked a question, which you of course have remembered exactly, and you may now answer it.

Robert Evans: I think your question related to the aspect of there not being so many people with off-road parking, so how do you make provision available for them? Certainly in this city, in London, that is an issue. It is also an issue in many cities across the UK. The availability of charging infrastructure in supermarkets, shopping areas in market towns and leisure facilities is certainly helpful, but obviously if you do not have home parking you are at a disadvantage compared with other motorists. So it is partially self-selecting, in a way, but certainly in London and other locations if you have a certain amount of public infrastructure it will help those people who want to buy an EV to have one.

[Sir Oliver Letwin]

Q Have you looked at the cost associated for a DNO in London, say?

Robert Evans: From our perspective, no, we have not. We know that UK Power Networks have done extensive study work in their projects, and we know from dialogue with Western Power Distribution that they have also looked at the same. Some of the councils here in London—for example, Hammersmith has a scheme that is looking to leverage the street lighting—

[The Chair]

Will you speak up a bit, please?

Robert Evans: Sorry. Hammersmith has a scheme that is looking to leverage the street lighting in order to provide charging for residents on the street. Part of that is largely around civil works and some of it is around the electrical works. The DNOs will be able to advise in these cases whether the low-voltage network needs reinforcing, but otherwise it is predominantly a matter of civils and equipment. Members are developing charge points, and have charge points, that can charge from street lighting, albeit that the power supply to that lighting is limited.

[Sir Oliver Letwin]

Q Has UKPN done an analysis?

Suleman Alli: Yes. It is very difficult to give you a definitive answer on the exact cost. The reason why it is so difficult to do that is that in order to come up with a cost, you have to understand the impact that it is going to have on the network. To understand the impact on the network, you have to understand when people are likely to charge, where they are likely to charge, the amount they are going to charge and the type of charger they are going to use. There are multiple permutations of that.

The only approach that we thought was appropriate to consider was to look at scenarios. Our peak demand across our three networks is around 15 GW. We think that up to 2030, when we might have between 1.2 million and 2 million vehicles, their peak demand could be between 2 GW and 5 GW—so between 10% and 30%. If you think of our track record over the last five years, we have connected 5 GW of distributed generation on our grid. That is equivalent to one and a half Hinkley Point Cs, without much fuss or bother. We have until about 2030 to work out how we are going to do this. My view would be that we are not complacent, but we are confident that we are going to come up with some solutions.

We think the Bill as it is currently presented provides us with a lot of help. In order for us to understand the impact, you need the visibility and the smart charging functionality. If you have the smart charging functionality combined with smart tariffs, you can start actually to deliver the infrastructure at lowest cost. I am sorry that I do not have an exact number for you. Anyway, if I did give you a number, it would 100% be wrong—but we are doing a lot of modelling and work to understand what the permutations are.

[Sir Oliver Letwin]

Q Have you looked at the other side of the coin—the peak locked-in capacity of the cars that are attached at a given time of day, say in the mornings or evenings, that could be used as a sort of battery resource?

Suleman Alli: That is a really exciting area of development at the moment. We are looking at it. As part of the Innovate UK funding, we are going to be supporting five EV trials, one of which is including a vehicle to be trialled with Nissan.

If you look at where distributed generation is connected in the UK today, it has mainly been at grid scale. A lot of our research on storage has been focused on grid-scale storage. We commissioned the largest battery in the UK at the time, 6 MW or 10 MWh, and we are very clear that storage can help peak shaving for the distribution networks at grid scale. We think that same concept can be applied to vehicles, but the trials need to take place for us to understand it fully. That is happening at the moment.

[Sir Oliver Letwin]

Q When do you anticipate results from those trials?

Suleman Alli: I believe within the next 12 to 24 months. We are looking abroad as well at other countries to see how we can generate learnings from those trials. Certainly, in the next 24 months we will start to see concrete evidence that we could present.

[Mr Hayes]

Q I wanted to bring up two or three things. The first is that you presumably agree with the changes we made from the first Bill, which was the forerunner of this Bill—the Bill that did not make the cut before the election. You will remember that what we have done this time is clarify the definition of automated vehicles, as a result of previous scrutiny. We have tightened that definition. How important do you think that is in providing confidence to the industry in respect of further developments?

Robert Evans: Automated vehicles are not strictly my area of operation, so I find that that is something that I cannot strictly answer.

Marcus Stewart: In some of the work that we have done when we have projected forward and looked at various energy scenarios, we see automated vehicles as having an impact on total energy usage. More automated vehicles, and clarity around the question, will allow different business models to come forward. Car sharing is more likely as part of that, and that will reduce the overall demand on the energy system, but we believe that it is still quite a long way out—maybe 2030-plus—before we start seeing any significant impact from that.

[Clive Efford]

To test—

Stan Boland: To test the vehicle.

[Sir Oliver Letwin]

Q To follow on from the hon. Member for Eltham, you are talking about level 4 rather than 3. Do you envisage that the machine’s design will be able to engage in autonomous conduct on every kind of road from the very first moment that they are launched?

Stan Boland: No, that would be a definition of level 5 in our parlance: something that could literally drive anywhere on the planet and be able to work out what every object was, what the semantics of every scene was, and the human behaviour in that part of the world, so we are definitely not saying that.

[Sir Oliver Letwin]

Q So a level 4 vehicle has some of the aspects of a level 3 vehicle, in the sense that there will be certain road conditions and certain kinds of roads where it needs to hand back to the human driver.

Stan Boland: No, I think it would stop in that case. In the behavioural model, we were able to bring up a system that works in a defined geography and in defined driving conditions, but if one day the place is completely wiped out with snow, we probably would not drive on that day. Our business model is to deliver a service. It is a service model.

[Sir Oliver Letwin]

Q So I am driving along a motorway where your system is happy. I diverge on to a trunk road where your system is happy. I move from the trunk road on to a B road where your system is happy. It is a somewhat rainy or snowy day. I get on to a one-track road in my constituency and your machine suddenly decides it is not going to get me to my home.

Stan Boland: No, that is not the model at all. First, you would not buy one of these cars. This is a shared form of mobility that is offered in cities. You would not buy it because the sensors and the compute you have to put in that car make that prohibitively expensive. It adds some £30,000 to the car.

[Sir Oliver Letwin]

Q So these are city-only cars.

Stan Boland: City-only vehicles.

[Sir Oliver Letwin]

Q And they are available to drivers not as a vehicle, so to speak, but as a service on certain days of the year under certain conditions.

Stan Boland: Probably all days of the year, but there may be times when humans probably should not be driving, frankly. In those conditions our vehicles would not stop just like that, because that would be unsafe, but they would be able to be carefully brought to a slowdown to stop safely.

[Sir Oliver Letwin]

Q It is basically like not being able to get a cab.

Stan Boland: If you like, yes. We think there will in any case be remote supervision so that it would be possible for a control centre to be able to monitor any cars that are stopped and then perhaps carefully move them to some other place. We are expecting a remote control room with perhaps one per 30 cars or something that would be able to take over and carefully manage the car. We are also expecting the cars to have a limp-home system, so if there is a catastrophic failure there would be a limited amount of capability where the vehicles could—at quite a low speed and with warnings—find their way back to a service centre.

[Mr Hayes]

Q I have three questions. First, you made an interesting case in response to questions from my right hon. Friend the Member for West Dorset and the hon. Member for Eltham about what you see as the likely development in autonomous vehicles. I will put two scenarios to you, and I would ask you to describe the most likely one. There is an instinctive, intuitive view that autonomy will grow gradually, partly because that is more likely to lead to public acceptance. So rather in the way that assisted parking or sat nav or cruise control have become increasingly routine, other aspects of autonomy will be added to that. Autonomous vehicles will sort of creep on us.

There is another view that we may go straight to a kind of autonomous vehicle. Indeed I have looked at some of the R and D on that. As you may know, there is an entirely autonomous vehicle at Greenwich supported by Greenwich council, with some Government funding too. That is a vehicle that travels on a straight run of road that is entirely autonomous. You get into it, and it does what it says on the tin. Which of the two scenarios is the most likely, in your view? Or are they most likely to develop in parallel?

Stan Boland: They are developing in parallel today, so I think that is the state of affairs. The first of those can be characterised as the view of the German car industry, which is that these things will happen, but in 2035 or 2040. In the meantime we can just keep adding these features, keep selling people more features, and keep selling cars that people buy. However, I think the world was really shaken up by the challenges we saw in the 2000s and the emergency of Google cars and so on, as well as the idea that it was within touching distance for science to deliver fully autonomous capability in a relatively meaningful timeframe.

That really is the difference between level 2 and level 3 autonomy and what is really a huge jump to level 4 and level 5. Our entire business is predicated on level 4 and level 5 being the dominant model. We think that that is the dominant model for getting to a situation of safety in an urban environment. Significant amounts of algorithms, computer models, training data and sensors are involved in achieving this, which will considerably increase the cost of the car. We estimate that getting the car to human levels of safety will add a further £30,000 to £40,000 to its cost. That is not a car that people buy. That is definitely a service, and if it is a service then it is fully autonomous.
