This has bothered me for quite some time. I live in Southeastern PA. We are not living on the frozen tundra nor are we living in a place that even resembles one. So please tell me why if you don't have an infant or a sick child or an elderly infirm person getting into your car at 7:00am do you feel the need to 'warm up' your car?
Today it was about 40 degrees when I was out walking G-dog. Not freezing, barely cold but as I was walking by houses I saw many cars with their engines running in the driveways. I know these homes. I walk by them EVERY morning. I know they don't have elderly people or infants getting in those cars in the morning so WHY must they 'warm up' their cars EVERY DAY?
Did you know that it is illegal to have your car idling for more than 5 minutes in some states? You can be ticketed for it. Also, most car manuals will tell you NOT to do it as it does the car no good. Basically, all you are doing when you leave your car running that that is wasting gas and contributing to greenhouse gasses. I mean seriously, do these people not own coats or gloves? Is 5 minutes of cold going to kill them while the car runs as they are driving to their destination? I think not.
The next time I see this happen and it is not cold and there are no infants or elderly people in the home, I am going to leave a note on their car asking why they feel the need to do this. Maybe it will shame them into toughening up just a tiny bit.
