I'm an accident free professional driver too - what's your point there?
And where did I say sit bolt upright staring nothing but straight ahead? As a professional driver, I'd assume you know that giving driving your full attention is about surveying your surroundings, taking in whats in front, behind, and either side of you; cars, pedestrians, weather conditions, etc, taking them into account and adjusting your own driving to suit.
So, as a professional driver, with all the above in mind, you endorse counting cars with their headlights turned off, memorising the age, gender, ethnicity, make model and colour of car, frequency of "offenders over a given distance" as suitable, and responsible, behaviour given the weather conditions?
