Things some people need to be told because their common sense failed to do so..
"You just suck at driving"
"Learn how to set up a car"
"the race is not won in the first corner"
"that mod motor still is not going to help you in the stock class"
Not intending to hi-jack the thread but feel free to add your own :P
and a personal favorite for the really stupid.. "another 2-3 grand and you just might get that 3rd place"
