This experience is truly not worth it if you are not a complete amateur driver.  The cars are great, but the instructors will not allow you to drive them to their full potentials.  The instructors simply did not shut up when it came to yelling sub-optimal instructions at every corner.  I wish I had a roll of duct tape for their big mouths.  Here are some examples:  They would tell me to brake ridiculously early, and drag the brakes softly into the corner instead of step on them hard (which would allow me to get better lap times).  They would tell me to upshift 2000 RPM before the redline.  They would hit the brake in middle of the turn for me very frequently (Yes, they have a brake pedal on the passenger side).  If you did not listen, they'll pull you over to the side and have a \"talk\" with you.  This completely ruined the experience for me, because I was not a total noob driver.  If you are a complete newbie to the track and racing, go for it.  However, any decent driver would not appreciate the instructors here because they all assume you are a total newbie and are wired in their brain to give you the experience of a noob.
