That's pretty nifty.
I play Empyrion every now and then so I can fully appreciate the hassles with the block placement and trying to make vehicles. I recall that one of the items on the Empyrion wishlist was proper wheels so people could make ground vehicles and not just hovers and SVs pretending to be ground vehicles.
On a related note, I've never been fond of above ground bases in Empyrion, I always seem to start by digging a hole in a hillside and making a "bolt hole" - the fear of drone attacks is too strong!
(I play with high level of drone activity because they are such a good source of resources and pistol ammo).
