Thought about a few more myself:
1) When pulling up at an intersection stop on, or very close to, the white line dividing lanes - ie not in the centre of the lane. So if the car behind you doesn't stop it has space to go past. Just a habit that might help you not get rear ended at robots by cars that didn't expect you to stop, or where not paying attention.
2) On dirt always modulate your speed so that you can stop before the visible path in front of you runs out. So if you cant see far, go no faster than the speed that will allow you to stop on the path you can still see. This way if you are suddenly faced with a washed away road, a cliff, a truck parked in the road etc or any other obstacle that you couldnt see, you should still be able to stop in time.
3) On dirt, always hug the left hand verge on blind rises and blind corners, and be ready to head off into the veld if necessary. For some reason on dirt - people don't necessarily feel they need to keep left and you often get bakkies/bikes on the wrong side of the road going the other way - which is particularly dangerous on blind rises and blind corners.
4) If you are caught out and are hurtling towards an obstacle under braking, instead of locking up and just plowing straight into the obstacle, consider releasing the brakes and steering around the obstacle - under heavy braking you only go straight and you have very little control of much else. Releasing the brakes makes the bike instantly rideable again
