I am convinced of the need for better driver training and stiffer penalties where pertinent. I believe that speed limits should be revised in both directions as there are times when long stretches of say, here, 90kph on roads with excellent sight lines are monotonous and encourage robot driving and there are areas where the current limits are inappropriate. Another interesting aspect of this is road markings which are often bizarre and dangerous and seem to have been set out without thought to the geography of the road or its potential hazards. Just a thought.
