As a kid my mom ran out of gas several times, and it was always on the same road, which had a gravel shoulder. We'd be riding along, she'd pull off into (what I call "the rocks"), the car would stop and she'd say "we're out of gas". Since the car was moving along fine before pulling off the road, and I had no concept of how cars worked, I made the connection that pulling into "the rocks" caused the car to run out of gas. After making that connection, I used to scream not to pull into the rocks when she ran out of gas. My parents eventually made the connection as to what I was thinking, and instead explaining how it worked used to tease me with it well into my adult years.
