I would think a gradual adoption of automated vehicles could work since the sensors in place could easily respond to unpredictable human moves. Volvo already builds cars capable of stopping independent of driver action, but it is only effective at lower speeds. Our vehicles would need a lot more computing power and as many sensors as there are airbags these days. Would there be a set transportation frequency for car-to-car communication to be free from interference? Could people ever learn to trust their car as it cruises toward a crowded intersection, like the one in the video above? The politics would be horrific, so it would be a long time before anything like this moved forward. Still it is fun to imagine the possibilities science and technology can bring. We would certainly all be in for the ride of a lifetime.
