Hyberbole aside, how would that even work? The further away from work someone lives, the more "commute time" they get paid? That has perverse incentives:
* I no longer take mass transit because driving myself is slower and I get paid more.
* I move further away, and take longer to get to work, and spend that time listening to audio books. My employer pays all that time, I'm doing a leisure activity, and I'm having a greater negative impact on the environment.
