Smarter traffic signals to save time and gas
Employing this system will not only save drivers time, but fuel as well. Idling while waiting for a light to change at an intersection causes more emissions and all that "zero miles a gallon" time really cuts down on gas mileage. Additionally, accelerating from a stop to the speed of traffic uses much more fuel than maintaining speed. There is serious potential for a V2V communication system like this to save us time and money while also making our commutes greener, as long as there's no way to hack into the system to give clever people permanent greens.
