1. Keep distance. You should drive "3 seconds" behind a car while driving at all speeds.
2. Carry a first aid box, a fire extinguisher, 2 safety triangles, spare, jack and wheel spanner in your car at all times. Plus an empty jerrican (ya kubebea mafuta ikiisha). Accidents and emergencies can happen at any time.
3. Learn how to dim lights at night especially when approaching other cars or pedestrians. Some of us see poorly at night, so when you shine lights onto our eyes, even with our walking sticks, we'll stagger into a ditch.
4. Keep left unless overtaking. Don't overtake on the left. I think this is the most abused rule on our roads. Does the Highway Code still exist? Do people know that a rule called Lane Discipline exists?
Set out to correct the world's wrongs and you will most certainly wind up adding to them.
