The fact that your collision box is wider when falling backwards from being hit, and then immediately narrows back down when you stand up has cost them a LOT of lives, over the course of this series.
@shaunk: The amount of time they take talking about starting the run before they actually start the run take another test run also varies enough that what looks like is gonna be The Run in video length may just be a long preamble to a hilarious car crash.
