Of course, we all prefer high quality separate infrastructure.
But that would be heart of the problem. We have a borough that doesn’t do that. It provides shared use space and then allows access to be eroded, leaving nothing. Ignoring this doesn’t help anyone argue for better cycling infrastructure.
That isn’t reasonable, nor is it reasonable for private estates to create their own rules for public access, ignoring their planning conditions. That allows the council to shrug and pretend it’s not their problem.
