With the number of aides likely supporting/informing/advising him, he probably understood the law. Other factors -- lobbyists, big donors (big oil?), more vocal constituents -- probably influenced him. Or perhaps, this is just what he thinks is right. Texans can vote him out of office and the law can be changed. Doesn't make it right but at least this isn't necessary forever.

I was kind of taken aback by the fact that pedestrians have to yield to cars, even at intersections., in Texas. I'm glad that I live in a very pedestrian/bike friendly place.
