In contrast, modifications to roads and routing to support integration could happen in a few years.
What sort of modifications are we talking about molgrips? You still haven't really expanded on what you meant by an "integrated network"?
Do you mean the same kind of things I'm suggesting in my last two points above (20 zones, improving junctions for cyclists etc)? Cycle lanes? Or something else?
That'll really help ease the morning commute!
Yep. Three kids cycling and having fun, who may well indeed develop a lifelong enjoyment of it and choose bike over car for their commutes later in life. That's a long term approach. That's what it is all about.
