I find the safety obsession with self-driving cars to be amusing. Safety is the easy part. I'm sure they'll be able to make cars which drive themselves on highways and have as good or better safety records as humans in similar driving conditions. Programming them to not hit things and to avoid being hit by things is, I would guess, the simplest challenge right now. But, hey, build a
test site. Preferably with lots of public money. Program them not to play bumper cars. They still won't work in the way that's being sold to people. Besides, automobiles are a 19th century technology.
