I live in Texas. This assertion is true of most cities in Texas also. Houston is the largest population center in Texas with 6M+ in the city. Also Houston is a busy center for interstate and international commerce especially for trucking.
SF is only 1 million people and the dense, downtown core is not that big. Outside of the downtown cores of SF and Oakland, it's all just suburbs wrapped around the bay. And plenty of people have absolutely brutal commutes due to the sprawl.
The only difference is they commute from "another city".
