Not all modes of transit make sense everywhere. We should do everything possible to discourage private motor vehicle transportation in our city centers, that are already clogged with smoke-belching automobiles. Taxing automobiles who head into the city makes a lot of sense, as it reinforces the message of the importance of using transit in urban areas. While in more outlaying areas, private automobiles make more sense, in the city, it should be place of subway, bus, and train to get around — technologies that can move a lot of people around — not take a lot of space up and not belch as much noise, smoke, pollution as individual automobiles do.
