As the OP on this thread I don't think I'm a 'poor' driver, just an average one. I make errors of judgement occasionally and, on occasions for whatever reason, I'm not as good a driver as I am at other times, maybe that's distraction, state of mind, maybe lack of concentration, I'm not sure, but I defy anyone to honestly say that's not the norm and that they drive perfectly all the time. So the reality is, there is always a ready supply of drivers doing exactly what most other drivers are doing who happen to get caught whilst making the odd mistake.
