If you watch the slow motion on the first "crash" he did, looks like he spent most of his time on the ground sliding on his ass.....lolAlso this one, not quite as ballsy but still good.
Well one of the videos shows someone doing that..but the pull required was strong enought that the the jacket was not triggered....it just kinda jerked the guy back. I think the pull force has to be over 35 pounds , so you'd have to be iin a pretty big hurry getting off the bike to trigger the jacket.That looks pretty interesting. But knowing my luck, I would forget to unhook it before I got off the bike, walk away and set it off. lol
