I found this glitch wherein during a speed boost (from wings, headstart, or powerup,) you keep jumping and sliding until the boost runs out and still keep the speed from the boost. Catching up with the conserved speed is hard tbh, but it can make a WR with a great time save. Should this be allowed?

So here's the video of the glitch:

Nice find! I vote for allowing it - not sure how much of a glitch it really is, I guess the base mechanic to conserve speed for an immediate jump/slide is intended and makes sense, and this is just a clever usage of this mechanic. Also, it must be quite hard to control, as you already said.

I would look forward to runs doing this, as it is also fun to watch :-)
