Yup, I added the buildable bridges. It was my first addition, actually. However, that’s because it was really easy. It was basically making a new terrain type that you’re able to drive over, and then adding construction options for it.
Unfortunately, vehicles are a whole separate beast from terrain. I did the bridge PR all in the json and mostly adapted existing terrain/constructions. Adding vehicle storage would require proper storing of vehicle data, correctly rotating it in relation to vehicles, handling what happens to it when the sorting vehicle gets damaged, writing an exception into vehicle collision code to be able to drive them over another, and I’m sure there’s more stuff that I’m forgetting. It’d be a huge project, which is why no one is tackling it.
I do understand the urge to have a small exploration vehicle you can stash inside your giant mobile command center, which is why I did some expansions of the folding vehicle code. Right now, (in experimental builds of course), there’s about 2 to 3 times more foldable parts, including smaller batteries, alternators, a new foldable shopping cart basket, lights, etc, and it properly calculates volume for foldable parts. They’re still limited to foot cranks and hand rims for propulsion, but you can quickly weld on an electric motor if need be since you can leave smaller batteries on there. I know it’s not the full feature you guys want here, but it was a reasonable compromise instead of several days of coding and weeks of nasty bug fixing.
