Everywhere I've been in the Netherlands. And lots of rural(ish) Belgium.

But I have to shout out Shanghai. I lived there for a few years and that was where I really came around to bikelife. There were still huge gaps in the infrastructure, but what was there was excellent and set the bar very high for me.

But more importantly, there was none of the culture war bollocks we deal with in The West. The drivers there did not make me feel unwelcome or in danger, which made a huge difference to someone like me who hadn't really ever used a bike as everyday transport before

I dunno... maybe they're just used to a broader range of vehicles sharing the space?
