on the other hand, the above poster is correct. too much focus is on passenger cars. meanwhile, commercial trucks, trains, ships, and airplanes contribute a big chunk of pollution and greenhouse gases but no one is doing anything to make them any greener or reduce their carbon footprint. and sports cars and supercars form such a small niche that their carbon footprint is negligible. it has become all about PR stunt and propaganda for car companies to brag about how much "green" technology they can show off in the autoshows.
