As semi-autonomous and autonomous cars become the norm, I would adore to see obtaining a drivers license ratchet up in difficulty in order to remove dangerous human drivers from the road.
I think it would be far more effective to make it easier to lose your license than it would be to make getting the license more challenging.
The absolute most dangerous drivers I see on the road aren't bad drivers in the sense that they're unskilled at controlling their car. I can't weave between cars at 120 mph or cross three lanes of traffic to make an exit I didn't see until the last second without killing myself, but I routinely see people do that. Sure they don't care about driving safely and/or following the law, but they're probably sane enough to pull it together for a brief driving test.
The other big category of dangerous drivers is drunk/distracted (texting) drivers. Again, most of the people engaging in these behaviors are probably smart enough not to do them during a driving test.
For your system to work, there would actually need to be cops watching traffic.
Since the pandemic, some cities just don't have as many police watching the streets as they used to.
For example, there is virtually no traffic enforcement in Austin now. You see the results with how much people speed now, and how awful some drivers behave on the road.
* Traffic enforcement capacity in Austin dropped significantly -- traffic citations fell about 55% between 2018–2022.

* As a result, speeding tickets, which once averaged 100 per day in 2017, dropped to about 10 per day by 2021 -- a 90% decrease.

But that's just science fiction. Cars are just going to be cars!
