Yeah, I kept trying to do the Crazy Dash, but it either works or doesn't work. I'll try spamming B and RT and see how it goes.
Also, in case anyone is wondering, it's pretty easy to do a Crazy Drift. All you got to do is hold both A and B while turning. It works well, but sometimes it changes the gear to reverse, which can get annoying.
