We don't learn much again about the actual social processes, but some considerations that were decisive. It seems data protection requirements played a role. I find it also important to note that an existing (commercial) data model was taken on by the city / the economic development department. As the controversies over the potential damage for retailers /shop owners are central for planning and transforming urban traffic, one could ask waht happens when data coming from a certain logic are then used for a different purpose.
