Years ago in the summer we kids would hitch hike out to a bay for swimming. [It was reasonably safe in those days.] At ten to thirteen years old we got to ride in many different kinds of vehicles.
One day we caught a ride in a Packard, about a '51 I believe. At our destination I could not find the door handle to get out. The driver told me to push the round button. I pressed this plastic button and the door swung open. I mentioned to the driver that it was a rather unsafe design. He conccurred and said that he had occasionally hit the button with his elbow, this in the days of no seatbelts. At twelve years old I was thinking what kind of nitwit engineer thought that one up.
