The glitch doesn't mean the game is rushed. Really, whether a glitch like this is in has absolutely nothing to do with if the game is rushed, because:
1. Every Mario Kart game has this many. Especially Mario Kart 64, Super Circuit and Wii.
2. Finding glitches in testing is way harder than people think. Sure, some random person found this glitch, likely by accident, but... the game testers probably either missed it (because face it, the easiest way to do the glitch is to go quite a way off the beaten track, to jump backwards to what seems like an earlier point), and glitches often creep in whenever other ones are fixed.
Basically, they might well have fixed a checkpoint issue found elsewhere (where you might get put from the final section to the second one, from the other end), but then in the process have introduced this bug.
Just a minor announcement to keep in mind.
