A Really Cool Way to Travel

I think a really neat invention would be a Car/Submarine/Drone/Boat. With the turn of a dial, you can change modes. It would have folding rods for every function but car. While in the submarine and boat modes, the propeller arms would fold in and hide the forward propellers, leaving the aft ones like you would see on an ordinary boat. Watertight wheels would also be provided, and these would fold in after the car was in the water or air. There would be a water/airtight body to the car, and this can stand a lot of pressure. The inside is much like a modern minivan, and it is very comfortable. The storage compartment is accessible from both the inside and outside, and all the machinery is accessible from the inside. A grabber arm and diving suits would also be provided for problems in the water. In the air, a landing could be made almost anywhere. I think it would be really awesome to be able to avoid lots more traffic and open up new water routes like rivers. You could be driving, fly onto the water, and switch to boat mode. You could also fly the whole way over trees and other obstacles and not drive on roads at all. You could even go boating by driving your car into a lake! Those are some reasons why I think a transforming vehicle would be really cool invention.
