Cars in the future, are (if you cant tell) going to need to be ran on alternative sources but provide the same luxery and performance that the cars today have. GM has came out with a couple ideas called the EN-V. Which is a small egg like car that rolls on two wheels, fully electric, and can hold two passengers. This isn't exactly the next ferrari super car, but hey, it gets the job done cheaply. Our ideas for future cars are mostly safety, efficiency, and self knowlege. Meaning cars that can drive themselves and cars that can park themselves.
