Sounds great, except I don't have too much trouble with this. Most of the time when I am coasting to a red light I get lucky. When the car is off at a signal light, I can tell when my light is about to turn green because of the other cars speeding past the yellow lights followed by perpendicular direction cars stopping.

I'm not sure that thing would pay off financially if they charge something like >$250 for it.
