Turn off your car!

I'm the first one to admit it can be very easy to stymie me. There are things I just cannot wrap my mind around. Like trying to ban drive-thrus. The idea is to cut down on air pollution created by idling. It's a noble cause but I just don't see it happening anytime soon.
However! I do not like to see a car idling especially when there's no large double-double with a cream-filled donut for a payoff.
Today I went into my local donut shop to pick up the morning java and there was a big line up of idling cars and right beside the door to the joint, sitting in a parking space, was an empty car, idling. What's up with that? Who chooses not to get in the drive-thru, parks, goes inside and leaves their car running? I am stymied!
And I can't count the number of times I've picked my daughter off at daycare and seen the cars of parental units sitting in the parking lot, empty and running! These moms and/or dads are inside, chit chatting with the marvelous daycare people and reuniting with their child and outside their car is chug-chugging, spewing crap into the air that their child has to breathe! Again, stymied.
I remember when I was a kid there was a commercial on television and the punch line (if you will) was "Don't mess with Mother Nature". I've never forgotten those words. The commercial was supposed to be funny but I've never taken those words lightly.
I'm nowhere near as environmentally responsible as I should be, but there are some things we just shouldn't do and how tough is it to turn the car key and take it out of the little key hole?
Stymied.
