AFICT, sedan is basically anything that’s not specifically something else.

Mostly, I used the robin because it has a very loyal fan base, for being such… an interesting little car. I was half expecting someone to jump on me being like “don’t you dare”.

In any case, the biggest issue is think timing the release. Like. With boulders or rocks or whatever, it’s really just a matter of geometry.

The CoG of a boulder in a sling (or gummy bear or dot, or whatever, really,) is pretty predictable.

For a car, though, it kinda pivots in a wonky way because of how they’re usually attached by the tow hooks, with a tether that gets released at the end of the throwing arm. It makes it hard to predict where the CoG actually is. (In the video I posted- and most of them, they botch the release, leading to it flying more up. I’m not sure how much more range they can get, but it was released fairly early. Maybe on purpose.)
