That doesn’t look like a race run to me, can’t see any number boards on the bars, might be open practise or an uplift perhaps…
And the jumper isn’t “Straightlining the trail” He’s on the “Racing line” (you can see the woodwork and tape to the right as helmet cam boy approaches) while the helmet cam wearer is bimbling along dabbing his feet and managing to make a hash of the chicken run…
TBH by the time the jumper could have even spotted the bimbler it would most likely have been too late for him to brake, he would have been commited and it was probably better to hit the drop and try to miss the other rider than brake late, tumble off the drop and lodge a chainring in that lovely THE Fullfacer…
What that vid does illustrate quite nicely is the pretty big speed differntial you often find between riders in DH (Racing or just riding trails)…
The thing is on a proper DH course you should always expect someeone to be closing on you fast from behind if you have to slow down/loop out for whatever reason I think the onus is on the slower rider to make every effort to keep the trail clear for faster riders, trail centres are a different environment, the focus isn’t the same for all users (Enjoyment for all skill/speed levels in a less competitive environment rather than Racing or Race practise),
Encouter someone slow on a descent at Afan, be patient, catch up to a slow rider on Astonhill Rlack run, politely bellow “Rider!”… simple
Great video, pretty scary miss…
