I'm curious what happens when there are two dozens of these in an active parking lot (or near each other on a highway) and they get false sensor echos. Then one day there will be half a dozen brands with slightly different sensors messing with each other via accidental interference and echos. Public has no idea how this stuff works and starts putting a little too much faith into it can lead to some horrible accidents.
