Hybrid electric vehicles work by doing something extra when we apply the brakes. We recover some of the energy that was spent to get the car moving in the first place. That energy is stored in the hybrid’s battery. Latter, we use that energy with an electric motor to get the car moving again. Hence, when we do a lot of stop and go driving, we get better gas mileage.
What is funny about the hybrid electric vehicle? In order to make the purchase of the additional hardware cost effective (the battery, the electric motor, the special breaking system,….), we have to have highways that force us to stop and go. That observation raises a some questions. Why do we have highways that force us to stop and go? Do we need hybrid electric vehicles because our government has built a lousy road system? Are government officials are pushing a problem they created onto private auto manufacturers?
