Like you, I have forty years of driving experience and I will admit, I am not without sin, but I used to vent most of that on the track, out of harms way. Equally, I drive a whole range of different vehicles so I get to see the road from a number of different angles. I do occasionally vent my spleen at our District and County councils at the in-adequacies and problems I encounter to do with their road management.
As this is a public forum, I think it is good occasionally to air views that the rest of the motoring fraternity may read. It may not get to the muppets on the road directly, but it might have a trickle down effect.
