Roadside litter in the UK is out of control, it is a national disgrace and embarrassment. The easiest way to deal with it is to create a deterant to stop people doing it in the first place, which will also save cash strapped councils a fortune in cleaning costs.
Any offence should result in four , six hour supervised roadside cleaning shifts as community service, over one month or a ten thousand pound fine.
