Overall:
I don't think traffic lights are considered 'idling more than briefly'; which is why it's not listed with 'fast food restaurant; stuck in traffic, train crossings'. I've always heard that two minutes is the cutoff: less that 2, let it idle. More than 2, shut 'er down. This may be an oversimplification.
The reliability of today's fuel injected/computer controlled cars make the imagined difficulty of restarting a moot point.
One little typo; "Idling engines get zero mph!", should be "..get zero mpg!"
How can we get more states (like Indiana) to consider this?
