> The more people uses the bus, the more buses there are, and they come more often (in rush hours you can take a subway each 5 minutes). The problem solves itself.

Unfortunately I only have direct control over my own actions, and very limited ability to influence the actions of other travelers or politicians. This isn't really an argument against the original commenter's point. If I get rid of my car and switch to public transportation, maybe on average the wait between buses drops from 1 hour to a millisecond less than an hour.
