1. Time flies quickly, and now it is 2029. By this time, I had invented a car.
2. The appearance of this car is almost identical to that of an ordinary car. Once you get on the bus, there is no steering wheel on the driver's seat, but a fluorescent display screen. When the display screen is opened, there are four buttons in different colors in the middle of the display screen: green, red, yellow and blue. Press the red button, the car can become an airplane; Press the yellow button to play music; Press the blue button to turn into a car; Press the green button to turn into a speedboat. As long as you have a car, you can sail freely in water, land and air.
3. There is a fixed box on the left. When you open it, you will see a transparent plastic shell inside. Through the plastic shell, you can see a red button. Open the plastic shell and press the button again. After three seconds, the car will turn into a rocket and fly. Don't worry about lack of oxygen.
4. This is the car in my imagination.
