I discovered a weird momentum change in 5.2. It seems when you dismount you keep going in that direction for a short bit now, in any direction.
Fly into the air, not high enough to kill you, preferably with a way to reduce fall damage. Look up and hold down both mouse buttons and then dismount/leave form and you'll fly up a few feet before falling down. You can do this in any direction.
It's rather useless, but the animations just makes it seem rather fun.
