Electric and I hope not self-driving.
There are few things more scary to me than the idea of trusting a computer to drive me around in dangerous conditions, or the possibility of being killed by either a driver AI bug/malfunction, or a computer car being hacked.
If you think one family of four careening into a hospital is bad, consider an intentional hack that causes hundreds of thousands (or millions) of cars to all go berserk at the same time, all around the world.
