Much Urban planning was involved in making it better for cycling though, and it wasn’t always great for it. Off-road cycle paths being a mainstay for the country with separate lights is the biggest differentiator, and took a lot work to get there, but now you can safely cycle the entire country!
Even Cambridge in England where I used to live (and is famous for thousands of cycling students and locals) Is laughably bad compared.
Northern Ireland where my family live has also transformed large parts with Greenways projects and it has been transformational, I ran along them, walked along them to shops and cycled a long way and it was amazing I thought.
