Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate she has made of the proportion of vehicle miles she expects to be autonomous by 2035.

Full implementation of the Automated Vehicles Act in the second half of 2027 will help ensure that any automated vehicles operating on Great Britain’s roads can contribute to overall improvements in road safety.

This technology is expected to be deployed gradually, and overall uptake will depend on a range of factors, including operators being able to meet very high regulatory standards, commercial deployment models, local consent for automated passenger services and the pace of market development.

For these reasons, the overall uptake of automated vehicles is highly uncertain so no estimate of the proportion of vehicle miles which will be automated by 2035 has been made.
