Not even discussing the price of gas, foreign war, or the environment, my commute home is unpleasant but it is always less painful for me than the others on the road. Because of our CNG powered Honda Civic I am allowed to drive in the diamond lane solo. Going through LA - Orange County at traffic time can sure give me an advantage.
Not to mention if I drove from here to Washington D.C. I would polute the equivalent of one teaspoon of gas spilled upon the ground.
