Seeking an answer to the question "Why are Danes happier than everyone else?," ABC News speculates that trust and bicycles make all the difference:

In Denmark, you can see trust in action all around you. Vegetable stands run on the honor system, mothers leave babies unattended in strollers outside cafés, and most bicycles are left unlocked. And perhaps the bicycle is the best symbol of Danish happiness. Danes can all afford cars, but they choose bikes —  simple, economical, nonpolluting machines that show no status and help keep people fit.

Since they give bikes their due, ABC gets a pass for neglecting the congestion pricing theory of happiness.
