I just want to add that it all depends on where you live. I don’t know what you mean by “most”. I would say most in cities with good bike lanes like Paris and Amsterdam would say most take the bike, or cities with great public transport like Tokyo would say most take public transport. If you live in a place like USA where it is dangerous to walk and the public transport is almost none existing then most would take the car. I think New York has ok public transport. But I don’t know, when I was there were sandy coming in so all of the subways were closed off.
