Ultimately, motorised traffic tends to disrupt other forms of transport as people get used to travelling longer distances to get to shops, work etc. This then results in out-of-town hypermarkets which pretty much require people to use cars to get to them. The resultant traffic inevitably results in congestion, so more space is assigned to building roads and facilities get built further apart which of course just exacerbates the whole congestion issue.

Maybe in the US which has gone all in on providing space for cars and their parking, but it's quite feasible in old European cities that are much older. Often it relies on reducing the space available for cars. There's good examples of how some European cities were able to change drastically.
The Netherlands is a great example as during the 1970s, it was heavily biased towards motorised vehicles. The "Stop de Kindermoord" (approximately "Stop the child killing") campaign was key to changing attitudes and nowadays, cities such as Amsterdam are held up as examples of designing for multi-mode transport.
