Assen - route from a 1970s suburb from the centre of the city. Nothing extraordinary. It could be anywhere in the Netherlands. This level of convenience is normal:
York - one of the top cycling cities in the UK. Again, nothing extraordinary. It could be anywhere in the UK. This level of inconvenience is not at all unusual:
British cyclists have good reasons to avoid cycle specific infrastructure. All too often, it's a mixed up, disjointed mess. However, this doesn't have to be so. It's really only a matter of design standards.
Dutch cycling infrastructure is made not as an after-thought or a box-ticking exercise. It is really meant for use. It joins up to provide a coherent grid of convenient routes which take you to all possible destinations.
This is true not only within the town, but also for longer rides, such as a 100 km ride that I made recently.
When cycling infrastructure gives cyclists efficient direct routes and promotes a high degree of subjective safety, that's when it can be used by the masses. For a high proportion of journeys to be made by bicycle, this attention to detail is not optional.
Don't fall for the idea that there isn't enough space in Britain. That's simply not true. Towns in the Netherlands used to look a lot like towns in the UK, as you can see from before and after photos of the very same city centre streets as appear in the first video.
