--- MPG Gain With Engine off at Stoplights? ---

[Clev]

My starter has at least 150,000 miles on it, so I'm leaving the engine running (except waiting at the drive-thru, railroad crossings, etc.) When I next have to replace my starter, I'll start keying off then.

This afternoon, I had to wait for a long train to pass at a train crossing and I switched the car off until I saw the end of the train coming near. Don't know if I have saved anything.
I did worry that if someone failed to see the need to stop and come behind me too closely for comfort, I might not have instant power to move the car forward a few feet. Chances of this happening should be slim anyway.
I am also curious about the legality of doing this. My intuition says that it is OK. I think it is a good way to reduce emissions and hence should be made legal. However, as in many other circumstances, I think for safety, the driver should do this only when the relevant situation permits.

I can't imagine why it would be illegal. I actually did it in front of a cop once. Don't think he/she even noticed.

Thanks! I feel reassured. I will probably do it again when I meet another train at a train crossing.
To me, it stands to reason that this practice should save some fuel and reduce some emissions.
