Just looks like he slid rather than rolled. It's all about the road surface you are on really, he was lucky there was no gravel. It's quite rare to still be 'attached' to the motorbike aside from anything else you try and get away from it because 'things' hitting you (or you hitting things) are going to do a lot more damage than anything else.That must be really painful but maybe he was dragged by the motorbike which made it so bad.!!!!!!!!!!!!!!!!!!!!!!!!!
I was once told by a surgeon that it's better to slide. "skin grafts are easy, repairing the breaks and nerve damage from your body rolling is much harder if not impossible to fix"she rolled rather than slid, which helps providing you keep your limbs in.
I've never slid, my offs on motorbikes have all been sufficiently slow that the thing I've hit (generally 'the ground') have stopped me pretty quickly. Then again I did MX, badly, for a few years so had plenty of practice with falling so I've barely damaged anything (one broken bone in a hand. Maybe a broken bone in a foot but probably not, I never had it checked out.) I guess compared to friends, living & dead now, I wouldn't consider any of mine big ones. My wife trashed two ZZR600's in the course of a years riding, one through inexperience (properly trashed, £3500 damage to a £2000 bike having pretty much snapped it in half) and one through over exuberance (theoretically trashed, but almost all plastic so we replaced it with second hand stuff) but walked away from both (eventually, first one saw her airlifted to hospital, but she walked out 2 hours later with no particular injuries). She didn't hit anything in either off, which really is the biggie.I'm lucky that in over 30 years of riding motorbikes I've never had a big 'off'.
It's the helmet debate with an engine. I've ridden to the shops in very little, it made me ultra careful and I didn't hoon about in any way, but felt surprisingly good. Similarly I've ridden a motorbike without a helmet, but generally slow stuff, on and off ferries, etc. I know people who would regularly ride in out of the way places sans helmet. It's all what you feel comfortable with, the vast majority of the time I'd not venture out without decent (although not necessarily motorbike specific) trousers, boots, gloves a bike jacket and a full face lid. But then I felt safest with that level of kit. There's no law against going out in a piss pot, pair of leather shorts and some sandals (aside from taste, naturally. Incidentally, something I have seen. The guy appeared from his house, got on his bike, screamed off down the pavement, skipped the kerb on to the road and accelerated off. Nutter in my opinion.)Unless you're a complete and utter twit...
