The flying car possesses four wheels and two wings. There is a very powerful engine on it, therefore, it has a top speed of 600km/h. Besides, with a super BDS (北斗卫星导航系统), you can go to any places in a short time even if you dont know the way yourself. Most importantly, it can not only run on land but also fly in the air. If you shout “fly”, the car will turn into a plane in 30 seconds. Then you can fly in the air. You will be as free as a bird. Traffic jams will never be a problem!
