[quote name='encendido5']Maybe they're using the snake technique? I just read it on gamefaqs, apparently you powerslide back and forth on straight roads to get lots of speed.[/QUOTE]
Yeah, I got the crap snaked out of me yesterday during a match. I did a Worldwide since I couldn't get opponents on any other mode, and I was matched up against one other player (his name was in Japanese). His record was like 140/5 or something crazy like that. He played Yoshi in the egg cart (same as me).
Anyway, the first race was Yoshi Falls and I swear to you, after the opening speed boost, he literally got a half track lead on me in 10 seconds. His cart was bouncing all over the track (it looks really strange b/c I couldn't see him powersliding at all). It almost looks like lag, but it was the dreaded snake master.
I noticed after that first match that he selected mostly wide open tracks that allow for a lot of room to snake back and forth.
Needless to say, he stomped me on every race except the last (Baby Park) - and that was because he drove BACKWARDS on that track - the gloating bastard!
