My MB is yet to be ready for registration but if were on the road now I'd prolly be idling all over the place......My shut off isn't working properly. I shut my cars off at train croissings or other traffic stops that I antipate will be longer than 20-30 seconds...I don't have a stop watch or anything I just shut it off if it feels right....In the Winter I'm drivong a diesel and its not warm yet I will let it idle...In my experience we (gross generilization of Americans) will start to observe less idling as fuel prices rise.
