After leaving a convenience store years ago, I was surprised that my 1991 Trooper was not where I left it. I looked all around and still didn’t see it until I caught a glimpse of it slowly rolling down the parking lot toward a creek. I hurried toward it and about that time it came to a stop just feet before it would have started a downward descent. I had left it in drive with the brake off. I mentioned the incident to someone nearby and he said that he saw my vehicle heading down the parking lot apparently without a driver. I guess it would be rather awkward to jump in someone’s runway car to make a heroic rescue.
