This past weekend I drove from NYC to Atlantic City (about a 3 hour ride), and for about 2 hours straight down the turnpike, I was only using my cruise control. I.e. "Cruise" to keep speed, "Resume Acceleration" to gain speed, and "Cancel" to reduce speed. Seriously, I drove about 2 hours straight without touching the brakes or gas. I would like to know if I seriously messed up my car by doing that?
