Richard Bourn, London campaigner for Transport 2000, said more needed to be done to encourage people out of cars, and to promote walking and cycling. Some 51 per cent of journeys in London are less than 2km, while 16 per cent of car trips are less than 1km. He said: "What happens when people move out of cities is that instead of being able to satisfy a lot of their needs locally, they need to get into the car to get a pint of milk."
