OK, we'll make it simple then.
If you make a self driving car and it kills a pedestrian, then you give the family of the victim $50 million, and a seat on the board. Forever. Every decision you make from then on will be looking into the faces of the people whose lives you destroyed, while they turn down your bonuses.
Also, I don't believe for one second that a self driving car is safer than somebody who should legally be behind the wheel of a car. If the sun is in your eyes, you slow down. If you can't see the conditions ahead, you slow down.
