Perhaps I'm stating the obvious, however regardless of the rationale behind various schemes and strategies we now see deployed by local councils and government, one of the biggest hurdles they face is changing the mindset of millions of drivers who have lived the majority of their life with the convenience of having a car/vehicle.its basic queuing theory. I don't know why it's so hard for the local government to get their heads around. Lots of people need to drive for work. We aren't all lucky enough to work from home or cycle to the office. If you make it hard, they wont stop driving, it's not a choice. it just gets hard.
Why should a road that one person lives on be declared a traffic free zone at the expense of another road where someone else lives?
I'm one of those people.
I've said similar before in related threads. Whether work or personal life, I'm sure we can all reel off lots of examples where using our own transport vs public transport wins hands down each and every time. For a whole multitude of reasons. This is the challenge they face. Essentially convincing the (driving) public to adjust their daily lives to ways that are usually less convenient.
In the long run they'll likely succeed. How? By making personal vehicle ownership and use more and more expensive and arduous.
