I had the pleasure of spending a couple of weeks in Copenhagen earlier this year. The public transport is excellent, there are separate cycle paths with their own traffic lights everywhere, and now you can rent an electric car if you absolutely need one. We used the train a lot and walked around many Km too. It was easy to rent a car when we did need one but if I lived there it is highly unlikely I would want to own one because the traffic is pretty bad and the public transport offered is excellent. The car is such a dinosaur when it comes to getting around a city.
