old forum windshield wiper thread had design that allowed better wipers. teslas other wiper patent was magnet based but i doubt that will be good against being stolen easily or moved by heavy debris liek hail. this laser sounds like its supposed to burn stuff out of the way and evaporate rain, and the burning would have to be not fire causing guarantee (like a cigar blunt that could light grass on fire if its burning too much) . it would probably be a array of laser rather than robotic turrets behind a layer of transparent material so the turret joints dont get stuck b/c of larger debris that cant be simply burnt.
very difficult to do, looks like shitpost to make potential investors hope they have a trick in store when market pushes them to innovate more
