I hope not. From someone who has never done a track day, and still wondering if I should or not, this video has put me right off!
As the others have said, don't be put off. If they were all like this, no one would surprised by the level of attack and sheer numbers out on track.
Do what I did, go on a club day with a mate who has a pestige marque. I went with a Jaaaag club trackday and because my car was worth less than two of their panels, they were much more scared of me than I was of them
