Your tragic emails about runaway automatics reminded me of a true incident, circa 1960. A friend had a wealthy uncle who had an automatic Rolls-Royce. One morning he drove out of his garage but stopped when his wife called him to the telephone. He left the Rolls ticking over still in ‘Drive’. As it warmed up and the oil thinned, the revs rose a little and off it went down his drive that terminated in two massive stone gateposts. My friend gasped and said, "Did it run into the gateposts?" Uncle Billy replied, "No! Luckily Hilda had left her Jaguar in the drive and it ran into that." How the other half live.
