ADAS + human driver seems enough to solve most of the shortcomings of both human and robot drivers. Full self-driving doesn't strike me as necessary to prevent deaths.
Automatic braking alone is a huge deal: if you're a bit late in braking, you get a warning. If you go past that, brakes auto apply. When configured correctly, I don't even notice it's there 99.9% of the time...and the times I do I'm glad it's there, because the beep pulls you out of a momentary distraction. The only problem is not every car on the road has it yet.
Except I had to turn it off for my Ford E-Transit, because it will freak out at nothing. Sometimes it screams at me for cars that aren't even in my lane that suddenly slowed. Sometimes it misjudges a ripple in the crappy asphalt here as an obstacle I'm going to hit. There is a high chance its going to brake for no reason at all and cause an accident.
I left the warning system on, but I will never give it control over the brakes.
