Solving it all with one fell swoop

I've come up with the solution to the current fuel crisis, Americans' obesity, global warming, and traffic jams all with one idea. We need to revert to Flintstones'-style cars: powered by our own little feet. Think of the carpooling! No one could text while driving! We'd all have kick-ass legs! Well, except for me. I'd pay someone to pedal me.

I'm incredibly bored. I think I might do a myspace survey... I apologize in advance.
