The future of cars to come is extremely exciting.  There are many different types of vehicles that are out there.  One day, hopefully, we’ll be getting around in flying cars just like on that cartoon The Jetsons.  There are many people out there at the moment who are trying their hardest to figure out how to get us to that point, however.  The future of vehicles in the United States is even more important because of the nature of the recent gas crisis in America.  Increasing numbers of Americans are becoming frustrated with the rising cost of gas prices and are desperately looking for alternative ways that they can save money by not using gas.  In recent years, there has been much research done on electric cars as well as solar powered and even hydrogen-powered vehicles being used to save energy as well as recycle resources. This is one of the major considerations that inventors are thinking about as they come up with new designs for the future.
