Google Has Patented A Tech For Self Driving Cars To Interact With Pedestrians

The patent, which was filed in September 2012, was granted in November this year. It describes ways to show messages to pedestrians, such as a red flash light, a display sign reading STOP on the left side of the car when it detects someone trying to cross the road or even the possibility of a robotic arm which will wave gestures. It also outlines a speaker system which may play messages such as “coming through” or “safe to cross” while unsure of its surroundings.
