You’re driving through a bustling city and to the astonishment of other drivers, every intersection displays a green light just before you reach it, allowing you to drive through in bliss. Sound too good to be true? It’s not. It could be you thanks to a new gadget that has traffic control officials worried. What if two people had one at the same intersection? Havoc and chaos would be wreaked in abundance, but man would it be convenient if you were the only one.

I was once told you could flash your brights at traffic lights, mimicking the flashing lights of a police car, to make the light turn green. I tried it several times and it never did anything so I’m inclined to believe they were pulling my leg.

Another way to get past a red light is the U-turn. When you see a red light, take a quick right, then do a U-turn and either go straight if you wanted to turn left, or take a right at the intersection if you wanted to go straight. Of course it only works if there isn’t much traffic, and that’s where that gadget would shine. It could be the middle of rush hour and it would still work, and at $300, it’s less expensive than the king of radar detectors, and ever so much more powerful.
