You could have started by finishing reading my comment - it wasn't very long, and it highlighted [housing] density.
You could also imagine that in 2009 we didn't have viable electric vehicles, but in 2023 it's easier to electrify a bus fleet than hundreds of thousands of cars in a given metro area.
You could also wonder why buses are so underused in America, the land of underinvestment in bus routes and overinvestment in car propaganda.
Lastly, you could consider why you chose to lash out at buses when I said "mass transit". Is your point to vilify all mass transit by picking on the weakest member? Do you only have a single data point on buses and zero on other forms? Or was it just the fact that you didn't really read my comment? Perhaps it's something else. I'm being meaner than I need to be. It's just that I get a little prickly about watching cities and ecosystems die for the profits of crooked car dealership owners.
