No one is going to buy into your hypothesis hinting that a plumber or electrician who carries their tools in their truck as part of their commute isn't part of the common man. It's simply a semantic game, trying to frame a definition to meet your extremist viewpoints.

It takes a serious disconnect from reality to make the statement 'There's no reason that anyone should need to use a personal car for commuting inside urban areas.' Either someone remarkably rich or naive.
