Especially with the the recent addition of a number of folding parts! </shameless self promotion>
It wouldn’t work for anything with an engine, but foot cranks and hand rims are both foldable. I’d like to add a few more simple cloth parts too (foldable storage, tiny battery system, maybe even a bladder to store liquids like a waterskin…)
But yeah, coding that would be a pain. It’d have to account for storing and loading the vehicle, rotating it inside/behind another vehicle, damage to the parent vehicle and resolving it to the child vehicle, and plenty more stuff I don’t want to figure out now.
