I mean I get what you're saying as an as-long-as internet user, but that's a bit like saying "I know how unsafe cars are so that's why I don't have one"
Los Angeles is an outlier, but it still has trains and buses, just less than I remember San Francisco having. If I were offered a job in Dallas/Ft Worth I'd honestly look into public transportation there beforehand. I cannot stand driving through and in those cities at all.
