In terms of the video, the camera guy was a bit whiny, an idiot for doing that little loop thing and could have totally diffused the situation at the bottom but bumble bee guy is a f***head. I say this mainly because of the bashing at the bottom but I don't see how anyone could be arguing that he shouldn't have let camera guy past. I'm firmly with YKYMF in the opinion that logic should always prevail. It would have literally taken 2 seconds for bumble bee to pull over and let him past verses 3 minutes of frustration for camera guy being stuck behind the whole run. For f*** sake just get out of the way for a second.
And on the argument between who should yield between a climbing and descending rider, I see both sides of the argument. Sure in a perfect world the climbing rider should be able to keep his momentum and keep climbing with as little interruption as possible, but in reality, if I'm climbing and and see a rider belting down the track in front of me there's no way in hell I would ever put my head down and keep pedaling expecting that they're getting out of my way. This is because I have a firm grasp on the laws of physics. The descending rider is travelling a probably 5 to 10 times the speed and is fighting gravity when trying to stop. The amount of ground they're covering when getting off the track is likely to be 10+ meters and there's every chance that they're going to axe themselves on a tree or something. As a climbing rider I'd know that I can probably find a couple of meters on the side of the track where I can still keep pedaling uninterrupted and I can stop on a dime if needed. Long story short: maybe the descending rider should stop but there's every chance they physically can't, and a climbing rider always can.
c'mon man, it just common sense. you don't step out on a pedestrian crossing if there's a semi-trailer barreling down the road, with no hope of stopping. so, yeah, anyone with half a brain would get out of the way if someone is coming downhill and can't stop. the point is, if the they CAN stop, and the trail only has one ride-able line, the rider riding downhill should stop to let the climber continue, as most of us who ride techy steep stuff know that is often impossible to get going uphill again once you put a foot down, and lots of people don't want to walk up hills, preferring to ride them.
on the flipside, if someone flies down a known busy 2 way trail (esp on a weekend) in such a way that they know they can't stop if some other rider is climbing up the hill around the next corner - well, that's just plain irresponsible.
as for rockshox guy and camera dude, i reckon i'd not want to meet either of those two riders on the trail. i very rarely call people to let me past while trail riding. In almost all cases, they can hear me coming, and they either pull off to let me past, or they keep going. If they keep going, I figure that I'm in not that much of a rush, and either wait until the next good opportunity to get past, or if it is a good DH/fast/flowy bit I don't want to waste going slow behind someone on, I stop and wait. Sometimes 30 secs is all is needed, have a drink, regroup with mates. geez what's the rush? if it was a race, it is a different story. i come across guys like rockshox guy at enduros occasionally - they just don't want to let you through, as they figure you can wait until the next fireroad, but that is ages away, and their speed is way less than you'd be going. I don't go repeatedly screaming at them though. I just find the next opportunity to sneak past and take it, even if i have to right off the track to do it.
camera dude yelling out "mate" within such a short time of the first call would had probably been enough to put anyone off-side. for all we know, rockshox dude had every intention of pulling off the track after the next corner, but got riled up by the impatience of camera dude. and it wasn't even a race.
