I'm really on the fence about this. Like on paper, this sounds like a decent idea but the way this starts makes me feel like the kid is gonna hit the concrete hard. Even though the boy doesn't get hurt outside of having his tooth yanked out this video is wild. The mom saying "Open your mouth!" had me in tears. When I have kids I'll just let them stick to tying the string to the door like we used to do. Sick car though brah!
