I haven't been to Denmark so I can't compare, but I agree there is much to be learned by looking at how other countries fare. In the densely populated Netherlands we are facing very serious gridlock problems now with cars clogging the highways and railways at full capacity. We can't keep building new infrastructure (highways) at the pace we did before, because - besides being very expensive - we lack the space for it. New solutions may lie in promoting remote work, carpooling and shortening home/work commute distances. I also suspect that bicycle infra will be developed even further (e.g. with bike highways) as they take less space and are less disruptive to the landscape.
