Are you dizzy? The RUF yellowbird is an oversteerer. Do you know what oversteer is? And if you don't believe me hopefully another GTP member will tell you that the Yellowbird is an oversteerer.
EDIT: Check this out. The guy with the OP (Opening Post) is complaining about the oversteer.

EDIT 2:
"Easily the worst handling car
in the whole game, The RUF
Yellowbird in real life is a
motor icon known by many
car enthusiasts but in this
game its popular for another
reason OVERSTEER!!!!!!! It goes
to slide on every single turn
no matter what tyres you use!
RVR have won in a major
tuning battle with this car (the
1st time we tried we lost )
Fixing most of the oversteer
problem and making the car
feel better! But be warned this
car is NOT for a beginner
driver!"
