I have a great deal of experience in both extraction and ejection systems for air vehicles. That said, I don't think that aeronautic solutions apply to LSR. I also have gone off my superbike at 120+ MPH and been a lot worse for the wear. Lots of people here are speculating about what they would or would not like to have attached to them under such a circumstance based solely on WATCHING VIDEOS of departures at 100 to 250 mph. I don't believe for a second that my falls (multiple) give me all of the answers. I do believe that I actually have some experience to balance the theory behind a lot of recent safety equipment "advances".
If (and that's a big IF) I decided to ride again and switched from superbikes (where I'm too old and slow to be competitive) to LSR (where age seems to create speed), I would personally wear the Dainesse system, but not the other "vest" or "jacket" inflatables. I believe that protecting against hyperflexion of the neck and shoulders and head impacts outweigh the additional hazard of the inflatable "shoulderpads" causing more tumbling than I have previously encountered.
I would absolutely wear a chute. On me, not the bike.
Having taken more than one too many trips down the asphalt on my leathers (I'll bring them to Speed Week for the doubters), I think that the faster we stop a rider with an aero decelerator (chute), the better. Yes, the rider can get hung up on the bike. IM<HO, a chute would decel the rider and put the bike out in front where it would have a harder time wadding up the rider. Perfect? No. Better? Yes. Could it all get tangled up in a big mess? Yes! Could it be better than what we have now? Bigger yes.
The scariest thing I ever saw was my bike passing me at 100+ after one get off while I was lucky enough to physically miss it. I remember thinking at the time, "That looks just like MY bike, except it's scratched." I wasn't scared then, but later, when my hands wouldn't stop bleeding.
