Do you mean in this particular spot? Because I don't mean that you simply can't speed boost from a standstill, I mean that you don't seem to have enough space in this particular place.

I found this seems to only be possible if you do a running turn around just as you bump the wall. Starting from a stand still would not trigger speed booster for me. I'm not 100% sure on this, but if I'm right this could have applications elsewhere so I figured I'd share this. I'm not even sure I'm the first one to find it.
