The Healthy Hybrid

I recently purchased a C-Max and was impressed by the fact that kinetic energy from the braking system could help recharge the battery.

As a professional who sits in front of a computer all day, it would be nice if my car had something similar to bicycle pedals that I could use to help charge the battery and reduce the amount of fuel I use. It could even be made with the ability to increase the tension (which increases the amount of attainable energy) as people get more fit.

Obviously, the pedal-pumping would be optional (sometimes you don't want to sweat), but an idea like this promotes personal and planetary health. I bet it would even curb road rage since the anger can be channeled into more productive energy.
