Light rail was shot down last election here in Austin. All the No Railers decided it would be better to build more roads to ease the congestion. I think cutting down on the number of autos will ease the congestion, but we're Texans, and we don't like to do anything unless we can bring a truck.
I admit, it's quite expensive, but I don't want us to be like Houston in 5 years. Luckily, the economy is taking care of quite a few Dell-exec SUVs out there.
