Audi made a big move in the self-driving car game this week

Soon, Audi cars are going to be able to tell drivers when a light will turn green. The new feature marks the first time an automaker has successfully launched something called a vehicle-to infrastructure (V2I) communication channel. V2I refers to any time a structure in a city, like a traffic light, relays data to a car. The traffic light timer will be displayed behind the wheel of the car. At this point, the system only works in Las Vegas and in Audi's A4, Q7, and A4 allroad models built after June 1, 2016.
