Chuckle, LOL.
Yes, there are buses. All of us have payment cards for the bus, although my kids are now using it the most. But, at least in this particular area, the routes do not run north/south and south/north. They only run east/west and west/east (depending on if you are on the north or south side of the street).
We live between two major E/W, W/E streets. Starbucks is on the street to the south of us. And since the buses don't run that direction it's either walk, ride a bike or call an Uber.
I'm not calling an Uber for what is essentially a five minute trip there by car, and then a five minute trip back. I'll walk. The grocery store and the pharmacy are all in the same area that SB is.
I do have a bike and at some point I'll start using that. But yeah, Phoenix (like almost every other major American city) is car-centric. The East Valley has light rail. But I live in the far West Valley. And it's the East Valley that gets all the good stuff, not us poor step-children in the WV!
