Not all city streets allows cars to be parket, but when allowed, we normally have date parking. You have to park on either the odd- or even-numbered side of the street depending on the day-of-month. This both allows the snow plow to regularly service both sides of the street, but also makes sure that there are enough room for two cars to just about meet.

But the above is mostly for the residential areas. Closer to the city core, every other street is often one-way. And getting into the "old-town" part of many cities, a lot of streets will be narrow enough that only delivery cars are allowed, and they may still not have much room for opening the doors. I live in a city that had a major fire accident 1888, so we lost most of the older buildings. During the rebuild, it was decided that all streets should be wide, which in this case means that two cars can always meet, even for the narrowest streets.

But even for brand new commercial and residential areas, our streets are normally way narrower than is common in USA. Maybe because of the large cost maintaing them since the ground freezes during the winter. On the road, where the snow is removed and doesn't isolate, the ground may be frozen two meters (6 feet) deep where I live, and when it thaws, it often thaws unevenly, which may break the asphalt. In the end, the roads often have isolating boards similar to what is used in buildings.
