That's the most ridiculous thing I've ever heard.
I drive 40 miles to work one way, about 50/50 city highway. Even on the worst day, I only get stopped by about 5 lights. I can't imagine it hurting the truck to start it 6 times (once at home

). If it did, we would all leave our trucks running when we go in stores, pump gas, etc.
I might have to give it a try, especially if gas hits $4 a gallon.
