I work VERY remote (my employer is in Austin, I live in Michigan), so public transit isn't really an option for that arrangement, but if I'm honest the only real reason I'm doing it is because of Austin housing prices -- I'd much rather live in an urban core within walking distance of work, but that lifestyle is unimaginably expensive in all the places where jobs exist. Instead, I have an aging 1940s tract home in a city 2k miles from work.
The housing crisis is also a transit crisis. We built most of our homes and businesses around the cheap automobile and infinite petro-energy, with the predictable result that we can barely afford to live near the places we work.
