In reply to GrahamD:
> We don't really have room for cycle lanes as the Dutch do
Don't entirely agree with this. Decent rebuttal here:
http://www.cycling-embassy.org.uk/wiki/our-roads-are-too-narrow-cycle-paths
Long story short, it's not like Amsterdam, Groningen and Utrecht were built from scratch in the seventies.
Also, a lot of the time it'd be fairly easy but we can't be bothered - a lot of the new developments South of Cambridge are being built completely from scratch and the access roads have a narrow bike lane on the road and a shared use pavement in the middle of a four meter wide grass verge, for instance. It's just that there was presumably no-one who know or cares about safe cycling involved in the planning process.
> do but we do have them and where we have them we just have to make them useable - make them an attractive option for cyclists
Agree with that. Although again, the fact that where we do have cycle lanes we still frequently fail to design them sensibly or maintain them properly suggests that "generally don't care" is more important than "don't have space".
Sorry, the "no space" argument is a bit of a bugbear of mine. I'm not saying that we should never prioritise motor vehicle capacity over cycle facilities, but when we do we should be clear that that's what we're doing, rather than treating the motor vehicle capacity as a given and declaring anything that can't work around that to be a physical impossibility.
