There's a fine line between the 'inconsiderate/ inattentive' drivers who are generally not paying the road the level of attention it really needs to drive at the speeds they are going....and those who deliberately do 'stupid' things when they see a P-car.
I have had the UK equivalent of the 'pick-up' driver.. Mr White Van.. demonstrate his acceleration off the line... his lane changing skills and performance of his overloaded van and so forth...all whilst driving the P-car..and yet when driving the Audi (a faster car) but a station wagon all I see are the inattentive drivers...much less aggression directed towards the Audi...
