Michael Palin , president of the pressure group Transport 2000, argues in this Open Space special that we must completely rethink our approach to transport, since the present trend for more and more cars and roads cannot continue. "The trouble is that we have got so used to having cars we can't imagine doing without them or even using them less," he says. "And it is increasingly difficult to manage without. As more people have got cars, public transport has been run down and walking and cycling have become more dangerous." And the fact is that a third of British households, despite the relentless increase in cars, are still totally dependent on those increasingly hazardous ways of getting about or on deteriorating public transport. Government policy is for the current trend to continue, but increased traffic adversely affects the environment, our communities and our health. In tonight's film Palin presents the alternative, and says that time is running out.
