Google was one of the first to get into this industry.It has been developing self-driving cars since 2009,and its new driverless car is called Firefly. The two-seater car has a cute,round shape.Its front end looks like a friendly face:The “eyes” are headlights,the “nose” is a laser sensor① and radar. Another group of radars,lasers and cameras sits on top of the roof and gives the cars a 360-degree “view”.They are linked to computer software that can identify② people,cars,road signs,and traffic lights,and thus tell the car to make turns and stops.
