#region Teleportation Notes
//Teleportation: WHY?!?!?!?!?
//(Not sure) Cars only teleport when making U-turn or straight turn, don't always tp
//Cars come out w/ same: NS - Y pos, EW - X pos as they went in with
//Do cars come out of the same intersection, despite a weird street?
//Is it just graphical?
//When a car makes a turn, both streets involved go orange until you press R.
//A random intersection and its streets can be turned orange w/ V.
//Finally putting this to rest. The problem was that distance was only measured on one axis. This was intended, but it meant that a car could intersect every intersection at a particular y or x coordinate at one time. Fixed it! 10/28/2017
