Could not agree more. Most city infra is not built for bakfiets-style bikes so they clog bike lanes. Paired with an electric motor they are dangerous given the speed they can go and their intrinsic weigh.
Most of the time I see people carry a single child or a bag of goods at best. Quite similar to how often people use SUVs for actual offroad riding, like never. Don't get me wrong, if you are transporting stuff on a daily basis these are great. But it seems for the majority of time a normal bike plus backpack or child seat would have been sufficient.
