Here is a good article comparing how Dallas and Houston have handled mass transit over the last 30 years. Dallas wins, but Houston is coming around. I find this particularly interesting because Houston, in the early 1980’s, passed mass transit enabling legislation before Dallas. However, the legislation, along with the taxing authority, was so contentious that a year later it was rescinded. Meanwhile, Dallas held their mass transit election; it passed and there has been no looking back.
