that's what happens when shit gets out of control. i remember when my club + a few other people were on our way to East Coast Nationals a few years ago and my hommie, josh barnes layed his s-10 out on all 4 corners, he got sideways but was able to hold it together and come out of it. it was pretty crazy because i was right next to him when things started to go wrong.
this happened because the guy was layed flat. the vehicle is sliding down the road with little to no traction (like in the snow, but worse) there is only minimal things you can do in a situation like this, and none of them is "just lift the truck back up." this is wrong because if you were to do that, you would go in the direction of the rear wheels (wall). you have to know what you're doing and be able to correct/make adjustments on the fly. it's kinda like drifting almost, just more difficult.
