A self-driving car would be able to provide a lot more information about how the accident happened.
This would probably except a lot of accident since they could prove that what they did was (mostly) correct, and it was either the other drivers' fault or something outside of their control.
Any accident this wouldn't cover, would undergo a lot of scrutiny, more like how airplane crashes are, than car crashes are today. And they would be able to fix it. Which would be a pretty good argument for self-driving cars.
The public aren't really aware of how much of a flight's control is handled by a computer and how much by the pilots themselves. Behind closed doors, literally.
I'm keen to see self-driving cars, but there will be a lot of opposition. Lobbying from trucker unions and the like will push negative stories and pressure decision makers, for example.
