I think a truly revolutionary driverless technology would be if you could buy sensors and a DIY kit from walmart, hook it up to your car to turn it into a driverless car.
A pickup truck from 1970s could be soon be driverless. Let a human drive when he feel like it but let the computer take over in dangerous and emergency situations where the human mind would be overloaded with sensory information and slow reaction speeds and lack of rational thinking could cause danger.
It reminds me of the new recovery systems being implemented in F-16s, when the pilot is passed out and plane sees imminent terrain danger, it will perform a recovery maneuver automatically.
This is the future, where AI does every possible thing for us. Even thinking. Every whim, every desires, every material can be experienced virtually via haptic controls, androids, 3d printed food of any taste and texture. We live in truly exciting times.
