Four decades ago, Austin, Texas, had a population of 250,000 and a reputation as a laid-back oasis of liberal politics and live music. Today, the Austin metro area is home to 1.8 million people and has some of the nation's worst traffic congestion.

The best way to experience Austin traffic may be from inside the police department's new helicopter.
