Unstable and dangerous at speed for sure but maybe possible. Those rear steel wheels would be detachable then the front two wheels seem to go into a fifth wheel type hitch. I also see two front jack feet for supporting it just like a fifth wheel trailer. I think it is an art piece myself.
I've been thinking about it more, and I guess there are a few ways you could evolve the design.
David Baillie is right, it looks like it is meant to go on a hitch (so the bulk of it is built onto a trailer, and then they added a front cabin with a smaller engine for smaller movement on its own. There are videos of it driving around a bit).
Then when parked, I guess you could do some type of stabilization (tie it down).
Perhaps a better idea would be to have the wheels on a hydraulic system that you could lower it fully onto the ground?
I was right, it's designed to collapse down for towing. It was built in California for Burning Man, so they had to haul it from Berkeley Ca, to the middle of nowhere in Nevada.
Once they got it to burning man, and set it up, it is self propelled with a max speed of 5 mph.
My opinions are barely worth the paper they are written on here, but hopefully they can spark some new ideas, or at least a different train of thought
