Texan72 Autonomous vehicles would NOT solve the problem of large amounts of traffic. It would just mean sitting in traffic while the car drives you.

That's an unfortunately 20th century mindset. Maximizing the coverage with autonomous vehicles that can sense their surroundings and communicate with each other as they travel would allow for much faster overall traffic flow even with the roads we already have.
We'll get to level 5 autonomy far sooner than Houston could lay enough track to make a meaningful dent in our people moving issues. With it's large spread out metro areas, the transit authorities of Texas should be leading the way in this effort. Instead, it's small minded efforts to built small trains in the city, and an even dumber idea to build a train line between Houston and Dallas.
