The hazard perception should be alright. You need to click the mouse (left or righ button) every time you see a "potential" hazard. ie, a car about to pull out, a child walking down the street. Then when a potential hazard DEVELOPS into an actual hazard you click the mouse again. The earlier you spot when the potential hazard has turned into an actual hazard the more points you will score. The size of the scoring window changes with each clip too. There is load stuff about it on-line and quite a few sites will give you free clips to practice on. Too many clicks or clicking in the pattern and you can be disqualified from scoring points on that clip. Personally, I think its more about getting your technique right more than anything. BTW I got 61 out of 75 and was disqualified from one clip!
