Hehe, nope. It's actually the opposite.

Don't get me wrong - they're building new bike lanes at a rapid pace. However, traffic, bicycles and pedestrians freely intermingle most places, which works because it helps reduce car speeds massively.

Drivers perceive intermingled streets as more dangerous, so they drive safer.

Much of Scandinavia is good at this, except when it comes to old city centres. And I believe Oslo has a large old and hilly centre.

So we're good at separating bikes from cars, when it's practical and when we have the space to do so. Gothenburg and Stockholm city centres are two bad examples. While Malmö city is a very good example.

While I haven't used the bike lanes in cities like Copenhagen, Stockholm, London or Amsterdam they at least look better than in Oslo. In London I was was impressed by the sheer amount of bike lanes, but then again, people drive like madmen there, so perhaps that evens things out.

To some extent. They have dedicated bus lanes with less traffic than the rest of the road and they have started restricting parts of the city center for cars.
