This was in the current issue of Reader's Digest:

As I drove into a parking lot, I noticed that a pickup truck with a dog sitting behind the wheel was rolling toward a female pedestrian. She seemed oblivious, so I hit my horn to get her attention. She looked up just in time to jump out of the truck's path, and the vehicle bumped harmlessly into the curb and stopped.
I rushed to the woman's side to see if she was all right. "I'm fine," she assured me, "but if the dog hadn't honked..."
