They never seem to look at the positive influence that surface transportation can actually have on urban form. A hundred years ago, a new streetcar line was installed on St. Clair Avenue in Toronto in a dedicated right-of-way. In 1928 they got rid of the right-of-way to make more room for cars; In 2006 they rebuilt it again, putting the right of way back.
I recently did a presentation on the effect of these changes on the neighbourhood at the Toronto Public Library; I live in the area. This slideshow is based on that talk.
