For them, a 30km/h crawler with overattentive collision avoidance system may well be useful. This is not much different to how public transport drivers have to drive.

I expect them facing same issues like trams and trolleybuses - terribly bad experience in traffic.

You only see risky people aggressively trying to overtake and scratching their paint, while leaving the driver no opportunity to move an inch.

A self-driving car is a mobile monitoring station; every such behavior will be closely tracked, recorded and possibly shared with the authorities. I think those drivers will learn to stay away from them.

For those of us who do drive it would be great to get that commute time back.
