Many years ago, I saw an interesting movie. It pictured the future life that people could fly in the sky by cars. Of course, I don't think it will happen in the coming time.
The change in cars is about the energy. It is said that the cars will use both electricity and gasoline, which can reduce pollution.
I think it is a great change for cars. More and more people have cars now and the gas they release brings heavy pollution to the air, which damages our health. The cars can use electricity in the long trip. When it runs out of it, then gasoline can be a substitute.
