Actually I can just imagine that I wouldn't mind a device to tell me how
far exactly the car is behind or in front of me. I wouldn't use it in
repacementment of looking with my eyes though. But it might be nice for
talking about those talegaters that come up behind you. Like "this guy
actually got within 10 feet behind me on the highway" for example.
Perhaps thats an extreme example though.
