ugh, Mark does it. I always get on his case about it.
I can understand letting the engine warm up for a few minutes when it is -30 outside, but he leaves it to warm up for a LONG time. I usually just get in and drive off, the whole while muttering and shaking in the cold. LOL

ugh! everyone on our street lets their cars run while they clean off their cars and/or shovel their driveways. i'm thinking, "dude, you're not getting in there in your underwear! you've got your coat on!" how much do they need to warm the car up? i dunno. it bothers me a lot whatever the temperature, but it REALLY kills me in summertime. like as if we need more smog, ya know?
