Lost Island Out of Bounds Teaser / Hydro Thunder (N64)

The first discovered exploitable Out of Bounds on N64. Does it save any time? Not a chance. Is it swag? Yeah. A writeup of the tips and knowledge I've accrued will come when I complete the first OoB race. I feel like I have a good understanding of the tricks so far, but I want a bit more practice before I begin making definitive statements.
