Designing city streets primarily for cars leads to many kinds of problems for the city's inhabitants.

I mostly agree with the article, but I disagree on one point: lowering speed limits. Most people need a way to get around the city quickly. That can be cars, or it can be buses; but if all vehicles are required to move slowly, neither cars nor buses can do the job.

I don't mention metro trains because few cities have developed trains to the point where they are almost sufficient without buses. The only ones I know that come close are Paris and Tokyo. Most cities can't afford to try to develop a train network that can get everywhere buses go.
