I've found some lap skip glitches and tested it to make sure it's possible RTA. I was wondering if you guys could make a category for it

Assuming the lap skip glitch you are referring to is similar to the Highway Zero one you found the other day, are you implying you have got this trick to work on other courses too? If it is only possible on HZ then it would be pointless to make a new category for, but if it can be done on several courses, then it would make sense.

Also, given how unique this glitch is, I'm requesting that you create a guide/tutorial which thoroughly explains how the glitch works and how to pull it off. It may be possible humanly but if nobody knows how to do it then that defeats the point and nothing can be done with this.

Not just Highway Zero... Bingo Party, Sandy Drifts and Deadly Route. There is one in rampart road but so far it looks like it's a TAS only skip
