Well, there are mainly 2 types of players on MK online, those who play for fun and those who only care about winning. I know the latter will do almost anything they can to win, including being as far ahead as they can so if they get blue shelled 3 times on the last corner of the last lap, they will still win, but I still laugh when the guy in 1st is clearly pwning all of us, way ahead and yet he still chooses to snake -.-
Anyways, I just play for fun and only snake myself if all other 3 are doing it, as I need to perfect it whenever I can for offline mode!
