I still don't know how to "wave dash" in Rocket League, even though I consistently stay in the Grand Champion rank. It's more than just jumping and flipping forward or diagonally hella fast, there's something to do with the rotation of your vehicle and I've never even been able to understand exactly what's going on through reading guides or watching videos. I guess you're supposed to be able to get like unlimited momentum because you're never touching the ground, like bunny hopping in an FPS? But my car doesn't ever seem to spin while mid double jump like I see happening in the videos of how it works so IDK WTF to do.

I don't really notice anyone ever going faster than me doing what I do, so maybe it's just a smokescreen; like all the players that are constantly rotating and flipping while flying for no discernable reason. I can control the flight of my vehicle without constant rotation; it's the same as trying to control a rocket in KSP so I only flip or rotate exactly how I want to turn or change pitch. It certainly looks flashy compared to how I play, but I don't see how it's making controlling your angle easier as many players claim it does. If you're constantly changing direction, how do you know what direction you need to be facing to go where you want to go in the moment?
