I don't understand why independent full automated self-driving is the goal. This just leads to competing "standards" so to speak. I think auto manufacturers should be working with governments to create smarter roadways and define an automated driving standard. You'd have smarter cars that would be able to link up in trains on the roadways. They'd be more efficient aerodynamically. It would be safer. You'd have "road ranger" style e-vehicles that could link up and charge you without ever stopping. And you could help fund it all using tax payer money.
