...Except there will be no disassembled minibikes in Alpha 17: only uncrafted ones. You’ll have to bring along a disposable workbench and place it in the middle of nowhere, wherever your teammate is. Or place a land claim so you can pick up the workbench, in which case you’re also making disposable land claim blocks...
I guarantee you, we’ll have many would-be rescuers that roll up in a 4x4, say “get in!”, and both of them get enormously frustrated when the stranded survivor can’t use the passenger seat they can see is right there.
It’s a two-fold problem, between the 4x4’s art creating an expectation of multiple passengers, and the existing workaround you mention being all but disabled.
