I'm not denying any of these and am absolutely not saying metros are bad, I'm just pointing out that in my experience there's very little chance "public transit commutes" are considered "more pleasant" than car commutes. They're mostly a different kind of unpleasant.

Even the best metro systems in the world are going to be hell when full to the brim (e.g. Tokyo's attendant pushing people so they pack tighter and the doors can close).
