The safety systems would work perfectly if the cars could communicate, or more robustly if they could be mechanically linked together for the “easy” (highway) portion of the drive. Imagine a lane with nose to tail cars all doing exactly the same thing. At exits (predefined stops) you could get off to change or stay on the same one. Put a little station there with bathrooms and food.
Maybe we could even replace that highway lane with steel tracks and the tires with steel wheels for lower friction.
Damn you just always re-derive the train
I was just jokingly rederiving a train instead. I think automated cars is mostly really silly
