Reminds me of an experience I had back in the early 80's I was driving a semi truck and at that time cruise control was very new on trucks, my DH was always teasing me because I was afraid to use it. I had a fear of it not shuting off when I touched the brakes. Well one day I decided to use it and the truck kept gaining speed I yelled very loud oh s...Husband came jumping out of sleeper He bumped the gear shift out of gear and got us slowed down. It was a mighty long time before I used it again
