Depth perception by triangulation is not used for objects beyond about 20 feet away. At that distance and beyond, one judges distance by the size of an object or its rate of change of size. I think it's safe to say that no one uses "two eye" depth perception for driving. Stan King phone: 201-386-7433 Bell Labs, Whippany, NJ Cornet: 8+232-7433 room 2A-111 uucp: floyd!stan
