Emergency vehicles are exempt from many laws and granted priority exactly for this reason - so that they reach you in 5 min, quite an impossible task given the congestion. I'm not sure about Norway, but definitely in Poland. Suburbs too dense sounds like a virtual problem. Concentrate like Singapore or Seoul, more density yet less traffic. Even more ecological if public transportation works properly. US population density is kept artificially low because everyone wants to own land. That is a "dream" sold by realtors, with obvious lack of focus on the costs of it.
