Self-driving cars are believed to be the future of driving. Companies including Toyota, Uber and Google are all competing to be the first to bring them to market.

However, car makers need to solve one problem first: How driverless cars communicate with passers-by, bikers and other drivers. Most drivers today use gestures to show their purposes. They wave a car into a lane(车道), or nod at passers-by and cyclists, to let them cross the street. But self-driving cars don’t have this ability. What can they do? US carmaker Ford and its partner Virginia Tech think they have the answer, reported Business Insider. The team is testing a method that uses light signals to show what self-driving cars are doing. For example, if a driverless car is yielding, it could flash two white lights side to side. A solid white light tells there are no humans in the car. A slow blinking light shows the car is coming to a stop. A rapidly flashing light tells passers-by that the car is about to speed up. To test the method on real roads, the team designed a special suit that looks exactly like a car seat. When a driver wears it, it appears to people that the car is really driverless. The team then successfully got more than 1,500 hours of data after about 2,900 kilometres of “self-driving” through busy cities. The data recorded how people interacted with a driverless vehicle. Ford says they plan to share the data with 11 other companies, reported dogonews. com. The company wants to work with other carmakers to design a signaling system that would be understood by all.
