I must be unusual since my actual door to door (round trip) commute would be 54 miles exactly, per day, which for me at 3 days a week would be 162 miles a week total. I have to drive my auto part way in order to avoid total burnout so my commute is only 17 miles exactly from my parked car to work. This is still above average it seems, according to most of the figures I am reading. Maybe that is why my hamstrings and glutes are so sore. I'm taking it real easy tomorrow.
I don't think we can effectively compare Dutch commuting to what we have in some parts of America. True, some Americans by virtue of climate (coastal California) or proximity to work can effectively commute daily a few miles to work. City dwellers are better off I'd say than many of us, especially if public transport is available. Many Americans live miles from work due to housing costs and the inconsistency of steady employment at one company. Our constant changing job availability forces many to commute long distance or move only to find their job changing yet again. Moving every couple of years isn't practical for many. This forces people who want to bicycle to find alternatives and sometimes there are none, in a practical sense.
When America stops exporting all her jobs out of the country and the economy stabilizes, we might start to see at least our cities doing things more like the Dutch. The differences between us are what make each so great.
Heck, some of our States are larger and farther apart that most European countries and we are not even talking about Texas, California and Alaska.
