Building vehicles is for robloxian idiots.
Firstly, stop flaming Roblox, neither is better
Secondly, 'building vehicles' is harder in blockland and in some ways, worse.
In Roblox, you create four wheels, a few bricks and stick them together.
In Blockland you make lots of sutff, flatshade, package, test, remake, test, package and so on.
If this were possible it would be good but I doubt it is.
The closest thing to this would be wheelbricks and a chassis brick which you could place with maybe a mountpoint on.
You could move bricks one tenth of a stud if you wanted to with the Editor Wand.
And so it wouldn't be able to move
