Consider the still-hunter. He takes a step or two, then pauses to look for sign. Only after thoroughly inspecting the cover around him does he take another step. Put that same guy behind the wheel of a 4x4, though, and chances are he simply charges up the trail, not knowing or caring what's ahead. His truck can take anything! Then, of course, a buried stump rips out his exhaust system and his wallet just got $500 lighter. That's not bad luck. It's bad driving.
