There is truth in that, but if you want democratically elected government (all levels) to adopt a policy of making it difficult to park in town centres without first providing good, easy to use alternatives, that can't happen. Because it relies on those who will be forced to do something they don't want to do to actually vote for it. Solutions have to take society with them. Personally, I'm very keen on good Park and Rides. The Bath one always gets my custom.
