For a long time when I was a kid, I thought that the wheels on my parent's car didn't move at all, and that the car just hovered an inch above the ground (I thought this because I was always IN the car whenever it was being driven.) I also couldn't tell that OTHER car wheels were moving because they were going so fast, so I assumed that the wheels of those cars were just flat.
