Traditional flat mirrors on the driver’s side of a vehicle give
drivers an accurate sense of the distance of cars behind them but have a
very narrow field of view. As a result, there is a region of space
behind the car, known as the blind spot, that drivers can’t see via
either the side or rear-view mirror. It's not hard to make a curved
mirror that gives a wider field of view – no blind spot – but at the
cost of visual distortion and making objects appear smaller and farther
away.
Hicks’s driver’s side mirror has a field of view of about 45 degrees,
compared to 15 to 17 degrees of view in a flat driver’s side mirror.
Unlike in simple curved mirrors that can squash the perceived shape of
objects and make straight lines appear curved, in Hicks’s mirror the
visual distortions of shapes and straight lines are barely detectable.
