Go rent a dirtbike, get it up to 45MPH, and slam on the brakes. See if you can stop in less than 10 feet.

Not a problem if I'm shedding velocity by running into the divider that separates the passenger compartment from the cargo compartment of the van!

If you put any useful crashpads in the van, you'd barely have enough room to fit the bike in the van.

Who said anything about crash pads? I'm not saying he did this on purpose! If it isn't faked (unlikely, I admit) it happened because he forgot the van was there when he began his run.

You'd also see the van kick forward from the impact of the bike in the van. That little thing called "momentum" doesn't appear to be conserved in that video...

You certainly would. Take a close look -- that van slides forward the better part of a foot, with the rear wheels locked and sliding, the front wheels turning, and the impact raises the van on its rear suspension about six inches. I'd say that ws a pretty reasonable transfer of momentum given about an eight to one mass ratio van to rider.

As I said before, it probably is faked -- but I'm looking for some visible flaw in the editing to demonstrate that, and so far haven't seen it.
