Having looked at the proposed regs, they kinda make sense.... if every Tom, Dick, and Harry were to be driving a self-driving car. If any schmuck with a bit of disposable income had a self-driving car, then overbearingly specific regulations might make sense. However (outside of a perhaps very rare to nonexistent hobbyist (this ain't a cheap game)), all of the self driving cars are owned and operated by large institutions. Since these institutions 1) have deep pockets, and 2) care greatly about their reputation, I can write appropriate regulations in a tweet:
"Self-driving cars shall be bonded for 2 million dollars each against damage to life and property, burden of proof lying against the owner."
Tweak the amount per currency or the value you place on life as you see fit, so long as the amount of the bond is whinging enough to keep out rich fools.
