There have been a bunch of links floating around recently about the German city of Hamburg’s plans to “go car free” in the next 15-20 years. For example this BBC Future article which references this post on Inhabitat, which then points to Arch Daily which finally links directly to the actual city planning site from Hamburg (auf deutsch of course).
Unfortunately, these seem to be just click-bait headlines. As far as I can tell (and I don’t read German) the real point of the plan is to create an extensive, connected network of bike and pedestrian greenways that provide easy access to the entire city, without requiring users to interact with motor vehicle traffic, “eliminating the need for cars.” Which is awesome! But also very different from “going car free”. There are plenty of cities where cars are generally unnecessary, but some people still choose to use them some of the time, and I don’t see why Hamburg would end up being any different after the implementation of the greenway plan.
