In the future, I think transportation will be greatly improved, including vehicles called flying cars. The byay is a very environmentally friendly vehicle, because it is powered by hydrogen fuel. Flying cars are very different from current cars in 2020. Of course because it can fly. It also has a lot of complicated components. So this flying car is also very expensive to buy. But I think scientists will find a way to make more of these flying cars. I hope this medium will be invented more.
