I used to watch commercials that warned people against "drinking and driving", and saying drinking and driving can cause accidents. I didn't know they only referred to drinking alcohol. I figured the hazard must come from the possibility of spilling your glass of kool-aid or whatever on the dashboard, bending over to wipe it up, and then crashing your car because you weren't watching the road!
A childhood belief about cars

you weren't the only one
80 of you believed this
- I used to belive that it was Illeagal to drink ANY beverage while driving, not just alcohol.— Emma*
- I used to think that the dangers of drinking and driving included soda, juice, milk, or water.— Rick
- Don't drink and drive! Literally. I would fuss at the driver if they had so much as a coke in their hand.
