> Would the city economy suffer? Maybe. Would it be a more pleasant place to live and work? I think so. The results of some European cities doing basically this suggest that the city economy likely wouldn't really suffer (and in fact could improve in many cases). That said you don't need to completely eliminate cars; blocking through traffic and severely restricting car parking can have much the same effect. If you can take a direct route on foot/by bike but have to take a more circuitous route by car, more people will do the former.
