This is a glitch I discovered, and have dubbed it the 360 wall spin clip, or the 360 clip, for short. Basically, it involves performing the 360 wall spin trick (which you get from beating Docks Chase 'N' Race) into a corner, such that the trick name shows up just as you reach the corner, this will teleport you up to the highest ground of that area, as well as bring you through walls. I used it in the video here to teleport from the bottom of Highrise all the way near the top. That's just the start, though, as you can even use this to get out of bounds in some areas, such as the Warehouse level.
