Google and Toyota have worked together to create a new smart car. It can run on the road without a driver. It drives itself. The selfdriving car hasn't been on sale to the public,so we don't know how much it costs. Another thing most people want to know is whether it will be safe enough to run on the road.

The selfdriving car uses electricity as its power,and it can t drive very quickly —the top speed would be 25 miles per hour. It is actually controlled by a computer system in the car. The system keeps on collecting information by some video cameras inside the car and a LIDAR sensor (激光雷達(dá)傳感器) on top of it. A computer processes the information and decides what to do. “The selfdriving car has only buttons for ‘go’ and ‘stop”so it’s very easy to use ,” an engineer of Google says. “And what’s more,it will make car accidents fewer and make the world a safer place. ” The selfdriving car has driven hundreds of thousands of miles in California,and it has only gotten into two accidents by human mistake.

According to CNN,selfdriving cars will also help to reduce the number of cars in big cities."Selfdriving cars would be able to send you to the workplace and then pick up another person instead of stopping in a parking lot. ”
