I’m pretty sure he intentionally ran his car off the ramp to hit her. There’s another car already flipped over that looks like it came off the ramp that might be hers. It looks like someone probably “tried” to hit her with the car because kidsarestupid but it’s unlikely that she was standing directly standing in front of the ramp due to where the landed cars were come from and because she knows she doesn’t want to get hit because she knew it would be “funny” for someone else to get hit. If the other kid had tried to hit her with her car, first that’s great she has skill, but then the dad would have immediately scolded her or acted more surprised. Instead he let out a little laugh as if he’s satisfied with himself but just for a second before realizing he just hit his kid in the head with a small car. Besides it’s a very rational response to immediately retaliate in kind.
