Do not idle for more than 3 minutes or else..

I am pretty sure it is 30%, I read an article in ski magazine called mr.turnoff about a guy who would turn ideling cars off in the mountains because there is a law against ideling because of mountains preventing smog from escaping. Think about all the truckers that let theit trucks idle 24/7, busses sitting at bus stops for 15min, people sitting in traffic, I would say 30% is an underestimation.
And you do deal with smog here, They have days where the air is so bad they tell people with asma to stay inside. And if you watch the local weather channel you would see that the air quality level is rarely at the good level, it is usually at the moderate level. Where do you think it is going to be in 5 years with all of the polution we create, US alone uses 1/4 of the world oil supply.
