Well perhaps some of the info is wrong, but then again, following the guidelines does encourage you to try to avoid falling and bumping into things. Those things cause you to lose time, so many racers could wonder why they only got an A when they scared a pretty decent score if it truly is a bit dependant on your track time. Sure, common knowledge. This should stay stickied, it helped me get 2 stars, and provides a good general overview of what to and not to do.
You may not know me, but i love you. >:D Mmm, yes. Wuhpuh.
