jruddIf you don't need help, why are you wasting time with a video game? If you're that good of a driver, why don't you have a ride with Prodrive or Joest or some factory team? Unless you have real racing experience, you probably couldn't drive your grandma's Camry at the limit.
Pretty much everyone thinks they are an above-average driver. Very few people are.
Cost and convenience directs me toward virtual racing but I have had profesional racing training and I have competed in several street and rally competition. I have been playing GPL with ease even before I ever stepped into a sports car so I disagree with you that you need real life experience in order to control a car with realistic physics on the screen. It just takes a little skill.
