A study released this week identifies white van man and BMW drivers as the most likely perpetrators of road rage. Drivers of red Vauxhalls and blue Fords are their most likely targets.
But what can we do to stop it?
I think the increase in 'road rage' is a fair reflection on current culture and people's attitudes to life - not just driving! We are all becoming more self centred, less tolerant of others and, worst of all, more aggressive. John Prescott's actions last week were simply typical of 21st century Britain: doesn't evolution worry you?
Philosophically, most people would agree that we should try to limit traffic growth to benefit the environment, improve the efficiency of our infrastructure and decrease driver frustration and resulting incidents of road rage. However, when it comes down to it, we are all 'George W's' at heart: we agree with the principle but when it comes down to it we will only play ball if it does not inconvenience us.
So traffic will grow and road rage will increase.
Rob Andrew, 36, chief engineer, Cornwall We need to introduce holistic costing to road, rail and air transport so that whenever a traveller contemplates a journey, they assess the real cost of travel and not just a misleadingly favourable marginal cost. Sensible transport costing will generate an increased market for public transport and so we would at last receive the services we need. We also need a real and effective commitment to planning safe pedestrian and cycle routes.
There are still too many illconsidered (if at all considered) cycle paths which were installed simply to use up a budget before it was 'lost'.
Chris Johnson, 46, senior structural engineer, Glos Quite simply the motoring laws in this country should be tightened up. Idiots who cannot drive (because they are incompetent) and idiots who think they can (the BMW wideboys of this world) should be forced to retake their tests after every offence.
Perhaps we should all retake the test every 10 years anyway:
has the Highway Code not changed in 50 years?
I suppose I am a direct action Prescott sort of guy really. This is not about driving, it is about modern society: the society where nobody gives a damn about anyone else.
Courtesy has gone by the wayside. Driving in a threatening manner should be a comparable offence to incitement or common assault.
Why should being in a road vehicle be any different?
Jon Goddard, 22, student, Manchester Ban all vehicles that you cannot see through, such as vans, 4WD's and trucks, from the outside lane; instigate zero tolerance speed limit enforcement; and fit limiters to vehicles to maintain appropriate distances between vehicles. We should also take some novel ideas from other countries. In Dubai dashboards bleep when you exceed the specified speed limit. In China countdown signs show the time until the lights change. And respray all red Vauxhalls and blue Fords.
