Audi’s Travolution 

You have to develop a rhythm regarding stop lights. You don’t want to completely stop just as the light turns green. Fortunately for those with a bad sense of timing, Audi’s Travolution takes it upon itself to keep track of when the light changes. Audi is currently testing the system.

It works because “Travolution” networks cars with traffic signals wirelessly. This way you will always know exactly when the upcoming light is going to change, which tells you how fast you should be going. It’s a great way to save fuel, and might even help traffic to move more efficiently. One day it may even come standard in all cars. Next the car will be stopping for you whether you like it or not.
