Transportation is indeed being implemented soon.
Yeah, the big thing about transport was the whole part where they would carry cargo, something Minecraft's boats failed on. Red51 agreed that we would see storage containers (sacks) on boats, and such. Horses would have saddle bags, and the like. Once wagons are properly animated to behave on terrain we'll also have those, among others. Train are also a big thing that we'll have to see how cargo hauling behaves. I would agree on adding mass into Rising World so we would have to drag trees to an external storage area (Medieval Engineers style) to require wood sleds and such. Horses, among others. Being encumbered needs to be a thing.
When it comes to transpiration, similar with Daboiye, wanting to have vehicles being treated with high respect so it feels highly special. They are special that they must be treated as such. To craft them outside a crafting station in parts, similar to how it's done in Wurm Unlimited.
When it came to buildings collapsing on itself Red51 shied away from such with how players would be frustrated. Maybe he'll add it, yet it may be on a heavy filter and such.
Blueprints shall eventually be survival friendly where you'll need to feed the construction site (with cranes and such) to eventually form them up from small to big sizes.
There's a lot to look forward to. So much so that the development pipe keeps getting clogged because of it.....
