So every time I'm racing against the Jalapeno's, I lag my ass off and wonder why everyone's going so fast. I kind of get the impression that my connection to Japan is so weak that the game doesn't register my movements with at the same time and that actually can decide the race if you're unlucky enough. I've had some crazy things happen to me involving lag that made no sense lol.
So while the Japanese are happily boosting ahead, I'm lagging behind. I really hate you Nintendo for lack of a region option. Only when I get with American players with a minimum of a few European players ( no matter what internet I use ) It's a "smooth" race if that makes sense.
