DURING my regular trips on the A9 I have noticed a marked improvement in driving behaviour since the speed cameras went live.

I find it incredible that campaigners are suggesting that travelling at the speed limit is slowing them down when the roads are quiet. A sense of perspective is needed here. Each road is different and you have to drive within the road's limits, not your own. To drive on the A9 like it's a motorway is inviting trouble.

Just last weekend I was cut up twice by cars overtaking me on two separate sections where two lanes merge into one. One of them was stupidly dangerous.

It's not the road, the cameras or the speed limits that's the problem, it's drivers who seem to think they are exempt from the dangers they put other road users into. In a word: selfishness.

Thank goodness I use a dash-cam, the police were very interested in both sets of footage.
