[NoCO2]

I have read that in some parts of the world, I believe Germany was the place specifically, the law is that you must shut off your car at stop lights in which you are at a stand still for more then 30 seconds. I know some people here do it as well and I have done this a few times myself while sitting at a light for a long time. I was just wondering, for anyone here who does it. How do you tell when to start your engine back up? I try to look at the other lights, but sometimes I just can't see them so that method is unreliable. The other question is, at what point do you see it a good idea to kill the engine? Do you wait 10 seconds, 30 seconds? Do you do it as you approach the light?

I'm just wondering because I'm always worried that when I do this I'm going to mis-read something I'm seeing with the light queuing and that it will go green and my engine will still be off. It's not that big of a deal because my car tends to start up almost instantly after I hit the key, but I just don't like feeling as if my efforts to save fuel is holding others up from doing what they need to do. (That reverse drafting thing is absolutely perfect for my situation)
