Voila! Red to Green

A friend once told me that you could get a light to change from red to green by flashing your high beams at the intersection or as you approached. Never did find out if it was true or an urban myth but now you can do it using infared. Pretty crazy that this is now available to anyone. What was wrong with the old light system anyway? Loud sirens and flashing lights aren't enough?
