About two-three months ago I was standing on the corner of William St and Sterrett St in downtown Houston. A bus came down William St. and turned right onto Sterrett St. and smashed the back side of a parked car on Sterrett. The bus just kept on going and did not stop. There were passengers on it.
We knew the guy who's car it was and we told him exactly what we had just seen, gave him the bus number and talked to his insurance. Metro denies everything and refused to cooperate, natch.
The situation in this article is of course much more serious, just throwing in my 2 cents on how I've seen Metro operate.
