I summarized most of it in the video, but yeah, let me know if I'm missing some aspect of this that makes it not as good as I think. Also, it might have NOTHING to do with surfing so maybe I'm dumb. But there's another glitch on train where it seems like players interact differently with walls, I thought maybe this had something to do with it. I know I've seen at least one more nade like this (where it kinda levitates because it hits the wall so may times. I'm u/counter-stupid on everything if you wanna follow!
