There is still a vast amount of work to be done...

For drunk drivers, a cop following a car can tell when the driver is drunk by the way the car moves on the road. How hard would it be for the car itself to detect the driver is swerving more than usual, or driving too fast or too slow, and then just slow down more and more, and stop?

Something like this could also work if a driver falls asleep, or has a serious medical event while driving and loses control.

I think it should be possible to have large sections of cross town roads and highways that would automate driving - once you are on the main road your car drives by itself, until you reach your exit.

Then we would only have to drive on sidestreets, in your own neighborhood for example, or in parking lots. It would be a cross between mass transit and having your own car. When your car is 'on the rail' it would be like riding on a bus or train.
