System uses in car internet to connect with traffic lights

My hometown had traffic lights on the main street with a little sign indicating that if went 40 mph and caught the first light green, you would likely make it down the entire street without stopping at another light. It was a grand design that was likely tossed in an effort to increase revenue by issuing more tickets for running red lights.
Audi has announced new technology that is a high tech version of that sign. The system is called Audi Traffic Light Recognition and the carmaker figures that the system could save millions of gallons of fuel.

The system uses in-car internet in a new way by leveraging Audi connect to establish a link between the car and the traffic light. The system is able to figure out the timing pattern of traffic lights (and the traffic lights in the vicinity) and maps those to an information system in the central instrument cluster that shows a virtual traffic light.

When the driver is stopped at a red light the Audi system calculates the time left before the light turns green and sets a timer for the driver on the display in the dash. The system also interacts with the start-stop tech in the car to have the engine on and ready to go 5-seconds before the light turns green.

In addition to saving fuel, Audi also thinks the system can reduce CO2 emissions by 15%.
Audi and the city of Las Vegas are working together on the trial of the system with 50 sets of traffic lights supported. Testing is also underway in Verona, Italy.

I do this manually already...

Perhaps I'm eccentric, mayhap a bit mad and a dash of obsessive, I work out the timing and patterns of all the traffic lights in my area inside my head. It helps me dance around everyone else gingerly. It also drives my wife insane when she is driving and stops at a needless light. Sometimes she wants to hit me I'm sure from all my babbling.

I don't do it to save fuel, though. I do it to save time. :)

time > fuel

I would gladly burn an extra gallon if it gets me home 30 minutes faster in this DC traffic.

30 minutes, you are lucky to save 30 minutes on a 200 mile trip.

Not if you live in a major metropolitan area. Traffic in Atlanta is FUBAR.

I do this too, it saves everything. Time, fuel, brake pads it all comes down to cost savings in the end.
