Earlier quoted context omitted.
This isn't my experience, but I understand some countries have overloaded public transit systems. When I've been in those countries, it's been simple enough to just let an overloaded train pass and grab the next one.
Ok but you let that train pass you might lose the connection to the bus at the other end. Or the next train or bus might not be for half an hour. Now you're late to wherever you were going.
I sympathize with people that aren't so lucky, but, if Taipei can figure it out, there's really no excuse elsewhere. Good public transit really is the only viable way to move people. The private car is, objectively, the worst.
