Based on what I've read, they sure don't know how to drive very well.
Besides, two of my younger brothers live in Houston, and they tell me the same thing.
That's an unqualified conjecture without any demonstrable substance to it. All you can say is that there have been a lot of wrecks with light rail - something that is generally true of any city with light rail because light rail is inherently accident-prone. That doesn't mean everybody who gets hit is stupid. A lot of the ones who got hit were innocent motorists who found themselves caught in the midst of a faulty turn signal system on a poorly designed track.
You did not answer my question, BTW. You demand that we build rail to your specifications. You do not live here so, once again, what gives you the right?
