Existing wing mirrors are ugly, hard to adjust, aerodynamically bad news -and they cost the earth when sideswiped by some white van in the 3:30 pub rush.
Today’s invention is to use a UAV, a small remote-controlled helicopter, which could carry a mirror and webcam and relay images direct to the driver. This could be stabilised against vibration and even zoom in on suspected trouble spots ahead. No more dangerous blindspots or invisible dips in the road.
When you want to park, the mirrorbot would help guide you in and then dock itself safely within the vehicle bodywork.
