As I stated, Mrs S, the object is to deter people from driving to the centre. Lakeside has 13,000 car parking spaces but you'll find it hard to get one as Christmas approaches. (Additionally, even though Lakeside is well-served by the M25 motorway and major A-roads, major traffic congestion often occurs at peak times0. Similarly, Bluewater also has 13,000 parking spaces (and good access). Westfield only has 4,500 parking spaces and is situated in an area of London which was struggling with insufficient road capacity even before the centre was built. The planning authorities insisted that visiting the Centre by car was to be actively discouraged.
