Blah blah blah whine whine whine. I consider finding shortcuts PART of the Mario Kart experience. Hell, Mario Kart 64 had several designated shortcuts as well as a few unintentionally exploitable shortcuts that were also approved and even ADVERTISED IN NINTENDO POWER. There's a reason Rainbow Road on the N64 is one of the most memorable tracks.
It's not like the computer players are going to use the exploit so it's only the multiplayer mode that's affected (mind that's half the reason you play a racing game at all), but these exploits are always high-risk, high-reward situations. I say if you're willing to risk taking the shortcut and succeed, you deserve to use it.
