To sell you need the car to be a better driver than the customer thinks they are which is a higher bar since most drivers think they are better than average.

Doubt it.

Even if they were much more dangerous, there is still a huge market. Safely, is arguably pretty low on the list of things that consumers care about.

The problem with self driving cars right now is purely political.

But even that isn't insurmountable. All you have to do is release in a low government regulation red state, like Arizona.

And then the rest of the country will follow, once everyone in Arizona starts using them and realize how awesome they are.

Maybe on highways in good weather conditions we are close, but the chaos of cities like Paris, Madrid, Rome with their narrow roads and millions of edge case situations will be a tough problems for self driving AIs.

I think you underestimate the effects of weather, amount of poorly lined roads out there, etc.
