I think gappers jsut don't realize what theyre doing.
I work at a skate shop and all the shoes on the wall face the same way, but it happens every day that someone will put a shoe back the wrong way. Looks so wrong and its obvious to me that its wrong. i think its kinda the same thing. gappers, i dont think they realize really what theyre doing and think that every one is kinda doing the same thing as them...
It is annoying and i'm not trying to find an excuse or make it acceptable, but i think mountains have found ways to make it harder for gapper to do this. At my mountain u need a park pass to enter the park. In the parks u dont need a pass, there are signs every where saying one at a time, wear a helmet, get out of the way, don't stay in landing area, etc...
