I believe that in the future, we will have a combination of three types of vehicles: cars, helicopters, and boats. That'd be a fantastic invention! It enables us to travel everywhere. And, at that time, we will not need petrol, but instead electricity. This also contribute to the environmental protection. This is a really convenient vehicle for us to go about on any terrain, in my view. Furthermore, if feasible, I'd like it to be able to collapse or extend at whim, reducing the car's total size. The price of these cars, in my opinion, will not be inexpensive, and I suppose it will come soon since our technology is so advanced now.
