I like reaction videos. If you don’t like them, don’t watch them, this isn’t complicated. I think football is stupid, but lots of people love it. It’s a big ol world, and it’s full of people with nervous systems all firing in different ways. Stop yucking other people’s yums.
Some of us are homebound with various disabilities. Some of us are too ill or too medicated to deal with actual social interaction. Reactions offer a parasocial experience that helps stave off loneliness. Lots of things that seem “stupid” turn out to be helpful for disabled people.
There are still some variables you haven’t mentioned. How high in the air are you talking, and will the car be dropped, or gently lowered? What kind of terrain is it? A flat, paved surface would be different than a field with rocks and bushes.
I seem to remember a toy car that kids could rev and set down, and it zoomed across the floor very well. A small plastic car isn’t the same as a real one, though.
