I used to think it was against the law to drink soft drinks while driving because of all the signs I saw that said "Don't Drink and Drive..."
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.
