Opinion of Oslo's decision to phase out the use of private cars in city borders?

[Cranberry]

I don't know about Oslo, but the concept of car-free areas in European cities is not a particularly new one - nearly every city here, mostly in the narrow medieval city parts, but not only, has pedestrian-only areas, and they can be quite extensive relative to the city's size. I'm guessing this project in Oslo might go one step further than is the norm thus far in Europe, but the idea is not really that brand new and/or radically shocking.

I obviously think this is a very Freedom Thing to do.

sounds like it's just in the downtown area.  do they have plans for what the people living their do with their cars?

Probably give them some parking spot outside the no-traffic area. Given the usual demographics of a European downtown-dweller, this should not be too many though
