A side mirror that eliminates the dangerous “blind spot” for drivers has now received a U.S. patent. The subtly curved mirror, invented by Drexel University mathematics professor Dr. R. Andrew Hicks, dramatically increases the field of view with minimal distortion.

This new mirror looks like a gently curved surface, but it’s actually made up of lots of tiny little curving mirrors pointing in subtly different ways, sort of like a disco ball if you ran it over with a steamroller. The resulting mirror surface is a smooth, nonuniform curve that provides a field of view of 45 degrees (as opposed to the 17 degrees that you get with a normal flat mirror) without any noticeable distortion.

The fact that this new mirror is absolutely perfect for cars and could prevent up to 4% of all automobile accidents of course means that it must be illegal to put on cars. According to the font of all knowledge and wisdom that is the government, cars manufactured and sold in the United States must have a flat mirror on the driver’s side.
