Looks like some of those animated cyclists were harmed pretty seriously. An investigation should be done!
But seriously, I agree with the recommendation to work on core strength, coordination, agility and flexibility. I think that helps with an instinctive tuck and roll, as mentioned in the video. I’ve noticed that when I’ve fallen on the bike (or on the run), that I tend to roll. I get multiple minor bumps and bruises but not a concentrated, single injury. Not that this is the only good reason to do core-focused strength and balance training.
