• 12．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 the market.However，carmakers need to solve one problem first：（1）

  Most drivers today use gestures to show their intentions.They wave a car into a lane，or nod at passers-by and cyclists，to let them cross.（2）

  So what can they do？US carmaker Ford and its partner Virginia Tech think they have the answer，according to Business Insider.
     （3）

  For example，if a driverless car is giving way，it could flash two white lights side to side.A solid white light would tell people nearby that there are no humans in the car.A slow blinking light would show the car is coming to a stop.（4）

  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 looks like the car is driverless.
     The team successfully collected more than 1，500 hours of data after about 2，900 kilometres of "self-driving" through busy cities.（5）

  Ford says it plans to share the data with 11 other carmakers，according to DOGO News.Ford hopes that in the future，every carmaker will use the same system of signals.
  
  A.But self-driving cars don't have this ability.
  B.It's a test for the company's self-driving technology.
  C.The data recorded how people interacted with a driverless vehicle.
  D.How driverless cars communicate with passers-by，bikers and other drivers？
