We have seen flying and amphibious cars in the movies. Flying cars are going to be here in the next few decades. Amphibious Cars are already here. The WaterCar Panther is a fast vehicle that transforms from car to boat under 15 seconds and can go as fast as 44 mph over water and 80 mph on the road. The car has a Honda sourced 3.7-liter V6 engine. It is made from lightweight fiberglass and can take abuse on the road. Looks like a lot of fun to drive.
