cool stoplight, which includes the progress bar around the light to indicate amount of time you’ll be stationary.

If you’ve got the amount of time you’ve got to stop in front of you, you can shut your engine off, wait, be calm, and turn it back on again when the time is almost up. This not only lessens the amount of gas you use sitting still, but it lessens the amount of crazy madness you have wondering if the stoplight is stuck, or just really, really long.
