One, I will never, ever buy a self driving car for as long as I'm able to drive myself. Two, if I ever do buy a self driving car and it comes down to a choice between me and a bus of pre-schoolers, that car better throw my ass off a cliff. I don't think I could force myself to do that just because our will to live is hard to override. However, if it's not in my hands, I think it'd be the socially responsible thing to do. Three, you mentioned an "avoid all accidents at any cost" paradigm OP, but I didn't see that in the article. Unfortunately with driving, there's no such thing. Automated cars or not. So many things outside of anyone's control can happen to cause accidents. The only way to avoid any and all accidents is to never get in a car.
