Sorry, there's a bit of misunderstanding here, my fault. I'm referring to metropolitan area population, not the specific city population. My city, Porto, for example, has less than 300k inhabitants. The metro area is, however, about 1.5M. In the context of auto traffic, or city services, the relevant number is the metro population, not the city proper.
