Except, there hasn't been a long period of consultation and a lot of people have had other things on their minds recently.
Some people are getting involved with the consultation but its clear an awful lot aren't, and that's why they're pissed off. Judging but what I've read elsewhere, many had absolutely no idea that this was even happening, let alone there was a consultation supposedly going on. And even if people did find the confusingly-named websites, how many people are going to know what a 'node' is when it comes to their streets?
Thing is, I'm all for LTNs, but the reasons and the benefits need to be properly explained to locals who may be affected by them, and it's not fair to keep dismissing their concerns when it's clear many feel very strongly that there really hasn't been a comprehensive community consultation in advance of these changes.
