Shame, this happens all the time
Yet another case of big government IT projects rather than mandating open standards and releasing data. I've just tried the Cyclestreets website, and it's clear they've got a lot done on a tiny amount of council grant money. It's not perfect but as a community project using open data, I'm sure it'll be pretty sparky over time. One route I tried was pretty much exactly what I do to work each day - another route near where my parents live up north was not so good, but it looks like one particular road isn't in their data yet, so it took me on a longer route. Good start, and I hope they get some funding!! The place searched worked pretty good for me ok btw.
