I can't remember for the life of me where I read it, but I remember reading a kinda sci-fi/fantasyish novel in my teens that had universal ai controlled cars, and the main character asked how they didn't get into accidents sometimes and the other characters were like "are you stupid? It's one centralised ai controlling them all" and that stuck with me as an obvious requirement for driverless cars.

Anyway I don't think any current driverless car creators read that book.
