The logic behind the Hazard Perception exercises is really quite simple.
1. Spot something that could develop into a hazard. CLICK! In real life you would be aware and watch out for something happening. Real life example. A car approaches the give way sign on a side street.
2. The something develops so that you have to take action. CLICK! In real life you will take necessary action to avoid an incident. Real life example: The car in the side street thinks he'll 'go for it' when there isn't space. You apply your brakes to avoid hitting him.
If you can't understand the idea behind looking out for hazards and being aware of things that could develop into a hazard the you should be a bus passenger, not a car driver.
Though a bit of practice with a CD ROM game won't help.
