car seat

what age did your child stop using a car seat ? my parents stopped using a car seat for us once we were 6-7. my sister did about the same with all my nephews and niece. though they’re honestly not the best role models. but when i google it, it says 12… idk i don’t think i ever met anybody who used a car seat till 12. that being said i’m curious what age you guys start using just a regular seat belt and no booster/car seat
