I&#x27;m not sure it&#x27;s <i>just</i> convenience but rather some combination of convenience, cost, and just preference. But your basic point stands. The vast majority of people will use public transit when it works better for them personally given their other options on a given day. This tends to most commonly occur in cities that have relatively good transit systems (for the trip in question) and congestion that makes the same trip by car relatively unpleasant&#x2F;slow.
