In Canada you have to get less then 10 marks agaisnt you during your test or you fail. You get marks off for shit like waiting too long to turn, stopping too suddenly, and you fail automatically if you can't parallel park, go straight on a straight road even though you are in a turning lane, and other shit like that. I failed twice before getting mine. I always remember thinking "What if I fail like a hundred times and become famous and a laughing stock?"
Glad to know that, no matter how good/bad you are, there is someone always better/worse than you.
