When I went to visit a friend at Apple in Austin, there was no bus that could take me anywhere near Apple's campus or any of the 4+ story residental complexes that permeate the area, yet there are a crapton of potential riders there!
TxTag is also a really poorly designed system, lacking any usage based pricing with TxTag highways often being paralleled by massive 50mph streets on either side.
The modus opeandi seems to be subsudize the living daylight out of cars, build no alternatives to it, and act surprised that Austin's traffic is worsening rapidly.
I now live downtown Minneapolis and it's been great, I even bought a condo and rent out my parking space for extra money ($200/month). My mortgage is less than my rent was in Austin (after my downpayment of course).
Meanwhile, yeah, the bus isn't as sexy as the train. Can we make the local bus a bit more sexy though? Could we add leather seats, tables for laptops, excellent Wi-Fi, clean floors, coffee vending, etc and make the bus experience better?
I also wonder about automation and how driverless buses might improve bus routes by making them 24/7, for example, due to lower labor cost?
Perhaps in part because of the cost, the people riding urban rail in Austin are definitely more often professional class, and the people on buses are more often not. I can't say for sure why, but the rail tickets are a little more expensive, and that is the most obvious reason. I have to think that at least part of why the tickets are more, is that the rail lines cost more to get up and running.
