What gets my goat is skiiers on a cat track, when they carve they take up the whole track. It's like their body stays near the middle but their skis go to the limits of each side making it damn near impossible to pass without being overly aggressive. Snowboarders on the other hand seem to have their bodies move along with their boards when they carve so you can find a good time to pass. But on the other hand boarders and more erratic with their carves compared to the skiers predictable turns.
the worst is racers who think the entire run is their practice ground and they have priority so they cut EVERYONE off doing those quick turn drills
