Some track organizations perform a tech inspection on your car before allowing you to drive, while others, such as Open Track Racing, assume you are responsible enough to have brought a safe car to the track. Either way, you should inspect your car one more time before taking it out. David Escudero is an executive chauffeur. He rented this '10 Cadillac DTS because it is the same model as one of his clients' and he wanted to know how it handled at the limit. Not trusting the rental agency's maintenance schedule, he checked the brakes, suspension, fluids, and retorqued the wheels.
