16.7 million people in England and Wales travel to work by car or van. This is 62.7% of the employed population aged 16-74. Reliance on the car is highest in rural areas (73.4%) but is also significant in urban areas outside London (67.1%). Even in the capital 29.8% of workers drive or take a lift. The numbers are revealed in an RAC Foundation report - The Car and the Commute - which takes 2011 Census data and compares it against land use type.
