There is a certain element of luck in Mario Kart... and it can be frustrating when it doesn't quite go your way. But, over time, skill wins through. Players like Matt, Dragon, Jazzem and Spindash know the game inside out and so, even if bad luck strikes them, over the course of a tournament they'll have the skills and knowledge to battle through and win.
Less skilled Karters such as myself have to fight for the scraps and, very occasionally, find that luck goes our way and roar to victory
. Even when we don't do that well, our experience will be improving race-by-race as we learn new techniques.
