The issue with Austin is most of the traffic isn't Austin residents. A shitty Austin house will cost $300,000 more than the exact same house 30 miles away.
Austin is quickly becoming one of the most expensive cities in the county. Which, by the way, is another reason it's being abandoned. Companies came here on the promise of cheap housing, and house prices in the area tripled in 5 years
So it's super expensive, hot, has shitty traffic, and it's a liberal island trapped in a state run by land developers and fascists.
