We will be moving to a house in the suburbs next year, and then we probably will get a cargo bike, as there we will have space to safely store it and the roads are better for cycling than the city centre.
Bikes also need a good amount of infrastructure, and most cities do not have that right now. Given its usually car drivers that pay taxes for roads (either a direct road tax or through fuel) it not really a suprise that they are designed for them.
