    Such a lightweight system would be very handy. However, the problem with all optical frequency (and thereabouts) systems is that they can suffer from huge path losses through clouds where Radio Frequencies will give return echoes through many layers of cloud. So you'd still need both systems on board, I think. (Not a problem, though)
    In self drive cars, an optical system would be subject to fog and heavy rain attenuation. But the upside is that such a system would drive you at safer speeds than typical over-optimistic human drivers can manage to do. 5mph would get you there safely, eventually and actually stop you when appropriate. Should give the passengers a rosy glow to feel that safe.
