> Counterexample: Arhus, Denmark. 91 km2 Counter-counterexample Rome, 1,285 km2 I'm from Rome Rome is particularly bad regarding cars (we are probably the western city with the highest number of cars per capita, 73 every 100 inhabitants, if I remember correctly), but it is also a very complicated city for biking. For two reasons - hills: they are not a problem for the majority of expert bikers, they are if the average age of the citizens is 45 years, most of them are not expert bikers and there are hills everywhere. Add to it the road surface which is less than optimal for biking in large areas of the city, including the city center (for many reasons, historical in primis, but also political, even more so lately that we have the worst major in the world). - distances: many people live very far from where they work, 1.5 million people everyday come to Rome for working, but live outside of it, most likely in the range 30-50 kms from the city, not counting the distances you have to cover when in the city (it's easily around 10kms, or 20kms total in a day). How many people can bike 100kms a day and make it alive? How long would it take?
