As a Pittsburgh resident who exclusively used bus for 5 years, this certainly seems like a reasonable take. In Oakland and Squirrel Hill the bus almost stops every single block - which always seemed kind of crazy. It's a _very_ common sight to see a beleaguered student miss their bus and successfully chase it down across multiple city blocks.
I will give the PRT (formerly Port Authority) a shout out though:
1. Bikes are quick and convenient to bring along
2. The numbering system is intuitive enough that you can almost guess how to get to new neighborhoods
3. Accessibility is clearly a priority, and they successfully serve many disabled people
