Audi's system allows the vehicle to display a countdown before a red light turns to green. Knowing how much time one has before the light changes to green will relieve much of the anxiety of waiting, Malhotra said.
The countdown will also appear on the dashboard if the vehicle determines it will not be able to make an approaching light before it turns red, to allow the driver to begin to brake.
While waiting for a red light to turn green, the display will disappear a few seconds before the light turns green, forcing drivers to pay attention to the intersection and determine when it is safe to proceed, said Malhotra.
