This brings up another good point. In Nemesis, we see the 'Argo' buggy do a couple of insane jumps, the most extreme one being at the end of its appearance, when it leaps into the back of the waiting shuttle. How did everyone come away from that outing without smashed crotches from all the bumps and jumps? For that matter, how did they not become hamburger meat on the back of the shuttle's bulkhead when they crashed inside it?
