This is 23 years into the future.
If autonomous cars take off in that time, the future may be that you won't be able to drive a non-autonomous car on the roads.
If that were to happen, it would be the motorways first. I would guess. But it would mean that deaths would be significantly reduced.
Found this info from 2015:
https://www.gov.uk/government/statistics/reported-road-casua...
Road deaths:1,732
Seriously injured:22,137
Total: 186,209 casualties of all severities
I predict attitudes are going to change where people driving on the roads especially when talking high speed will be banned.
If people aren't using petrol cars anymore then you won't have petrol stations every few miles, a full tank will become quite expensive as well due to lack of demand.
But hey, it's still a ways away. In my town there's an old sign at the entrance to the square saying that traction engines are forbidden. Today, cars drive through it.
What's normal today will change. Who knows how exactly, so enjoy it whilst it lasts!
