I am being somewhat knit-picky, because your point is: "Self driving cars only have to be better than humans who are already very imperfect" But... It isn't just deaths that need to be prevented. It is a combination of total damages, delays, deaths etc. If self driving cars take forever to make a turn or have other AI failures like driving too slow, it won't be acceptable to a large number of people. In addition, you will see a situation in the future where partially automated cars Level 2 or 3 are safer than current driving modes. That means that in order to go from level 3 to level 4, you need the car to be safer than level 3. I want a fully automated self driving car so badly, but I suspect I have a long way before I can hop in a car with no steering wheel and sip an IPA while being rushed home from a tough day at the office.
