The answer is to teach drivers to be aware of, and to show respect to other road users and pedestrians.

That means, no tailgating, no flashing of headlights (it's my road, get out of my way!), and above all not making unpredictable manouvers which cannot be anticipated by other road users.

The roads are for everyones use. If people are made aware of just how potentially dangerous driving can be, driving standards would improve and the roads would be much safer here.
