My dad was am IBM lifer, when they said they could wear suits that weren't black he wore a blue suit and his boss asked him if he rode the bus to work.
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.
