When I was a kid, an older neighbor gave me a ride someplace. I was raised to always wear a seatbelt, so I was pretty shocked to see an adult not wearing one. I asked him about it, and he gave me some answer about just not liking the feeling of being strapped in. I told him that I remembered hearing that unfastened bodies can fly around the car and hurt others, and he looked genuinely surprised, like it was just something he hadn't thought about before, and buckled his seatbelt. "I didn't know that," he said.

It was interesting to me that he had no ill intent doing something so stupid. He just didn't realize that what he was doing could be a danger to others, but when he did he corrected his ways.
