Motion, and/or proximity sensor. The motion is "relative" to the vehicle motion so even stationary objects appear to be "moving" to the sensor. A bit of intelligence will help to differentiate between objects that are "moving away" and those that are getting closer. And you really only care about motion that is within a certain distance. But the advantage is that it can have a much larger "field of view" than the camera. One has to distort the image (objects may be closer than they appear) in order to get a truly comprehensive field of view. With non visual sensors they can have a field of view that is extremely large.

I'm not "against" rear view cameras, it's more of a case that if this issue is important enough, they don't seem to be the optimal answer to the problem.
