Assuming you live in a locale with a reasonably efficient system. I've heard some horror stories about north american public transport. Other countries tend to do much better with timetables and routes.
Too crowded, too hot, there’s a decent chance of arriving at your destination drenched in sweat. Not to mention how absolutely gross the people sitting next to you will often be.
I’ll happily take a few parking fines every day rather than getting in the tube.
You should try expanding your horizons a bit.
You do have to ignore the people around yes but I don't find that a problem at all.
