I'm particularly referring to this video at minute 2:08. The author of the video claims that the other guy descending a challenging mountain pass (1) doesn't look too experienced, (2) may not be in the right gear, (3) undergoes "lots of axle articulation", and (4) is messing up the stones on the track.
Can any experienced off-roader here confirm any these claims or is the guy just spewing disparaging comments?
PS: To me, the guy going downhill seems to do all the right things, but now I'm doubting if I missed some subtleties.
