quote: When your car engine isn't running, it isn't polluting the air around you.
quote: For example, if I bought a Prius and drove 3,000 miles a year, instead of being enviromental, I am being quite the reverse. I required significant pollution of the enviroment to create a fuel savings technology I am not taking advantage off... that's easy example. For this start and stop, I personally don't idle very much. In a typical day I may hit 2 red lights for a total ~90 seconds idling. Do I save enough fuel to justify the extra pollution of the the technology? That's a legitimate question I think...
quote: I can do my own start stop by turning off the engine with the - KEY! And if I know the stop will be long I do do this now.
quote: What if it's really cold - say zero. I want my heat on if cabin temps are not warm yet. Some red light stops go up to 2 minutes.
