Had to go out to the pharmacy the other night at around 9:00. It was right around the time this strip mall was closing. When I got out of my car, there's a 20-25 year old woman who obviously was warming up her frosty car after an 8 hour shift. The temperature was just below freezing, and I noticed her because she was sitting in her car reading a book rev'ing the engine at what had to be redline. So I wait about 10 minutes for my prescription to be filled and I come back out. She's still revin'g the engine at redline. I watch this for about a minute, and consider going over and telling her how bad this is for her car....but she'd probably think I was some kind of freak approaching her in the parking lot late at night. Anyhow, at this point she realizes the engine must be warm enough, and she let's her foot off the gas pedal, the car drops to normal idle, she checks her mirrors and carefully drives away. This has got to be her standard practice....makes you really wonder about that used car ad. "Used car for sale..nice condition..lady driven" Right.
