If we set it up right[1] the cars share data/experience so that each one learns from the whole fleet. A novel situation will only be novel once, for one car, then all the rest will be able to handle similar future situations "by the book". [1] I don't think manufacturers of self-driving cars (and can we please call them "auto-autos"!?) should compete on safety, rather, I think it should be mandated legally that they have to share data on crashes with a view to preventing further crashes. Like the aviation industry, eh?
