This Start-Up Makes Sure Driverless Cars Don’t Run You Over

But unlike most self-driving test cars on the road today, Drive.ai’s system also includes an electronic billboard strapped to the roof, a bit like a digital highway information sign. It appears intended to reassure pedestrians that the car senses their presence, using words and emoji, according to TechCrunch. When the car is stopped it a crosswalk, for instance, the sign displays a “Safe to Cross” message, to reassure pedestrians that it won’t run them over.
