It's awful. I hate it. Passed it first time for A1, failed first time for ADI. Damn those sheep! Just click every time you see a DEVELOPING hazard, and not when you see a POTENTIAL hazard. To put it another way, treat the mouse button as a brake lever. Click every time something on screen would make you brake, and not when it would make you cover your brake just in case... Example: A car approaching a junction ahead and to your left is a POTENTIAL hazard. A car exiting a junction ahead and to your left is a DEVELOPING hazard. And lastly, if you see sheep, DO NOT RELAX. There are more ahead!
