Something more like a grappling hook that gets fired into the ground and the spiky bits spring out to anchor it in.In theory, or whatever, it LOOKS like it could anchor it down....but yeah, thinking about it, it is just making a hole isn't it, that strong enough winds would just pick it up, and that part, out of the hole.
So would COULD be used to anchor a vehicle down?
I'm not sure off the top of my head here.
The bit on the truck is literally just the auger from a post hole borer. Hey, I get how the movies work - it's all make believe. I just find this laughable is all
