All I really remember are the following rules back in the 90s:
1. The person on the right ALWAYS has the right of way, even if they know they will crash into you without slowing, it is better to be right than avoid an accident. I remember my instructor going nuts a few times when I slowed down because someone wasn't paying attention, and even if I had the right of way looked like they would hit me. Felt like a game of chicken!
2. Even if you are going 145kph, don't worry when the cops approach you from behind approaching you rapidly, just move out of the way and they will pass you at 170kph (I think the speed limit was 120kph)
4. Pay close attention to that car flashing his lights at you 2-3km down the road, because by the time you put your blinker on to move over, he is up your bumper!
3. If you can reach the bar to pay, we will serve you.
All in good fun, I loved my time in Belgium with the Mannequin Pis and would not trade my experience there for anything!
