... A day later, I flew back to Denmark. After appointments here in Copenhagen, I was riding in a car back to my hotel at the 6 p.m. rush hour. And boy, you knew it was rush hour because 50 percent of the traffic in every intersection was bicycles. That is roughly the percentage of Danes who use two-wheelers to go to and from work or school every day here. If I lived in a city that had dedicated bike lanes everywhere, including one to the airport, I’d go to work that way, too. It means less traffic, less pollution and less obesity.
