I was watching and thinking to myself, hmm.. I thought i remembered snowmobiles would accelerate much harder than that. It seems like they aren't accelerating very quickly, modern sleds feel like they are gonna jerk your arms off when you pin it on compact snow like that. Them I thought, hmm... I wonder if they do multiple levels of throttle governing systems to control the approach speed as precisely as needed, since it appears the jumps are more or less exactingly constructed, so it would just take a mechanism like a cable bicycle trigger shifter to mechanically set throttle stops to make a range of dialed in approach speeds. I think the work of the jump with these seems to be in the take-off alone, which sets the sled on a predetermined path (likely angle fine tuneable with blips of throttle or brake applied), but still, most of the technique seems to be in the take-off alone, with fairly minor effects to the sleds path once airborn. I think with the edition of small-ish electric (maybe low pole SR motor where the rotor IS the gyro flywheel to remove the powertrain to hubmotor simplicity) have very high speed gyro assemblies (to keep them light for the amount of space it takes up), they could gain the 2 axis tail-whip rotational capabilities, which would enable leveraging a humans arm strength to twist the bars while its on the very low friction/support medium of flying through the air, to rotate the sled and do massive snowmobile tail-whips to add new features to the types of jumps performed, and enivitably make the sport more exciting and dangerous.

I think the fine young men doing it would enjoy it more as well for the same two reasons.
Life is a time to gather experiences, before the 100% human mortality rate kicks in. Some people are happy to have a large collection of only a few types. Some people dont mind ending the experience gathering with a smaller collection, but do really want to have a few very intense and special amazing few. I think later option has a much better chance of piecing together the collection of experiences that equals forfillment in their time of life.
Some believe otherwise, and they might be right, I can only know the path that lead me to becoming forfilled and being at peace with the world and better prepared spiritually to die.
Remember, that awesome kid following his dreams was going to die. This was known from the moment he was concieved. Could he have managed to fit a lifetime of amazing experiences in a 4-5 year period of living as a professional Xgamer? Yes. Absolutely. I would actually believe some of those guys live in a day of emotional experiences and intensities of knowing the different limits of experiences exceeds what many folks would hope to experience in a lifetime, and thats the whole experience gambit, from rush to fear to thrill to accomplishment endorphin rush, to pleasure, to sadness, to guilt. Single days where the entire range of human emotional response causing range is exercised more than many would be lucky to match the intensities of from any events over there whole long dull lives.
That said, I tremendously respect Chalo's opinion, because on many things it presents an argument so out of my normal perspective on lifes point of view, that I catch it as a good philosophical check to think about, and it general always consists of good points, but I end up often disagreeing at the end of the internal perspective review.
Where I dont disagree with Chalo at all is technical advice related to bicycles. This guy is a amazing fountain of no BS empirically hard learned lessons of what methods work and dont work with bikes, and its a damn pleasure to have him donate his time to share methods of doing various non-intuitive bike mechanical theory and practice with us. My deathbike would still be having wheel problems if it wasn't for him telling me I was heading in the wrong direction with bigger spokes and needed tighter stretched than I even thought made sense to do. I likely owe him so big patches of skin that didn't get rubbed off in wheel failure related crashes that nearly stopped happening after taking his advise.
He also often helps me via PM with bicycle related advice for my perpetual bizarre projects I can't seem to quit building. Lol
