Then the metro should have paid the teacher more to make those congested commutes worth it.
And, there is definitely a distribution of commute times. Some very long. But your average commute is not two hours one way; the center of the distribution normalizes around some level of bearability, around 50 minutes in the US. Which, with bad congestion, might allow you to go 10 miles. But with no congestion, might allow you to go 60.
The reason I quoted distance is because commute times are relatively stable, the product of travel speed (congestion) times distance. And that's the point; if travel speed is increased, many people will choose to live further away, e.g. for a bigger house.
