Sensors and transponders better than cameras?
Yes, one needs camera input as well to deal with things like fallen rocks and pedestrians that don't come with transponders. (I rather anticipate a future with self-driving cars when sane pedestrians and cyclists *will* carry transponders, possibly integrated into their mobile phones).
But consider optical illusions. Despite several hundred million years' evolutionary honing, there are still situations where either you cannot quickly work out what you are seeing, or you totally mistake what you are seeing. (The latter largely accounts for the "invisibility" of pedal cyclists to car drivers. "Think bike" has limited effect on the lower levels of our vision processing. I've seen two cyclists collide because "invisibility" applies equally to the cyclists themselves )
Do we really think that a computer vision system will be better than the human vision system after a mere few years' development? I doubt it.
