It would be better if there was a standard calculation like:
Commute time = time it would take to commute by public transport from the nearest residential area that could house a family on the income of the worker in question
That puts positive pressure on improving cost of housing, and improving speed of public transport
And were they to try to play the system by getting high speed trams linking a poor, cheap area to the CBD, that would quickly no longer be a cheap place to buy
Realistically they could just pay fuel based on miles driven

Sure, but that’s overly complicated and not realistic by any means.
