I should stress that we pretty much agree on this. In Hackney, where I campaign, we are advancing proposals for quite a lot of modal filtering. I, too, hope that it'll be as popular as you say it is, but years of campaigning experience advise me to be cautious. We'll see.
As for cost, I thought you were advancing this for the whole country. It's certainly easier in London's Zone 1-4, but apart from the actual bollarding or gating (which would cost far less than 'in the low hundreds of millions'), there are other challenges to overcome. The key question is whether it can be achieved without generating more pressure for new road-building.
