This is a very legitimate question: In the US, where is it not?

Public buses aren't safe, clean, or timely. Where I am, it's 2.5 hours rather than a 26 minute commute by car. The only reason you ride one is usually if you are already in the proximity of your destination, especially if that destination is downtown. For all other cases, private or ride-share makes way more sense. We're talking buses here, not shuttles, light rails, monorails, etc.
