Having grown very happy with the radar for my bicycle, I'm growing more and more curious why we don't have more of those on our cars. I've seen the nice visibility affordances on some high end cars when you do reverse. Seems that the parts and sensors needed for that have grown considerably without people knowing? Direct to this, I'm surprised the light would reduce accidents by so much. That said, I don't see any reason not to explore it more.
