A childhood belief about cars

In my moms car there were little ashtrays on the sides of the doors that had a little picture of a cigarette on it so you'd know what it was for. The picture was so tiny, that when I was little, I thought it was a picture of a boat, and that you were supposed to hold on to it if a boat was crashing into your car! Then, when I told my mom my theory, she told me that the picture was actually of a cigarette. Til I was 9 I thought that was there for blind people who couldn't tell what the ashtray was for!
