I think it's difficult to judge your own driving. Who fancies taking their driving test again?
I do wonder if we will lose some concentration and perhaps skills as cars become evermore automated with things like park assist, hill start assist, traffic sign recognition, lane departure warning, adaptive cruise control, collision avoidance etc. etc.
On the other hand, there are that many road signs and markings in congested town centres that I have difficulty taking them all in and watching other road users and pedestrians at the same time, so any help would be useful.
In reality I try and avoid such situations which is probably what the town planners want.
