These vehicles remind me of turtles(designed for protection of what’s inside).
That also brings to mind the photo of a fence-post turtle. sorry but I do not have a copy.
I’m also positive that out there in Redneck land there are some that can and will design a V8 powered vehicle to attack and upset one of those monstrosities. An attack from the side by a wedged shape vehicle that could turn it on it’s side would do wonders.
My thoughts go back to the TV show, “Robot Wars”(?).
Wonder how it would fare against a D8 Cat?
