The other side of hybrids(Prius)

So everyone always screams that the hybrids the prius in particular get good gas mileage. Which then in turn in good for the environment. Because less gas is used. However, most people forget to mention how the Prius gets such good mileage. Not only the prius get great gas mileage it does it in a way that is healthy for the environment.  The government has given the prius a Practically zero emissions vehicle rating (PZEV) for short.  This means the Prius puts out  way less pollution then most cars on the market AND gets top notch mileage why doing it. I know that hybrids are not the final solution. but for the time being the government should push them. and true hybrids like the prius and the Toyota insight or civic. That get good mileage ie 40+ and emit very little. Not the SUV hybrids that get only marginally better mileage. For those, we should start moving towards bio-diesel hybrid combo. Watch the mileage soar and our not the oil companies wallets grow thicker and the amount of CO2 we pump out drop.
