This is our local OBahn system. It has an excellent safety record and it really does work very well.
German designed and developed and we were one of the few countries outside of Germany that adopted the system.
The driver steers the bus onto the track and then floors the throttle. He just sits back and the track steers the bus.
I can see a road similar to this for cars but you'll still have to drive the car on normal roads until you join the track and then the computers will take over.
