Rather bear those ills we have than fly to others that we know not of?

A classical rendition of the decision-maker's dilemma. From William Shakespeare's Hamlet, Act 3 scene 1, the famous soliloquy,
To be, or not to be--that is the question: Whether 'tis nobler in the mind to suffer The slings and arrows of outrageous fortune Or to take arms against a sea of troubles And by opposing end them. To die, to sleep-- No more--and by a sleep to say we end The heartache, and the thousand natural shocks That flesh is heir to. 'Tis a consummation Devoutly to be wished. To die, to sleep-- To sleep--perchance to dream: ay, there's the rub, For in that sleep of death what dreams may come When we have shuffled off this mortal coil, Must give us pause. There's the respect That makes calamity of so long life. For who would bear the whips and scorns of time, Th' oppressor's wrong, the proud man's contumely The pangs of despised love, the law's delay, The insolence of office, and the spurns That patient merit of th' unworthy takes, When he himself might his quietus make With a bare bodkin? Who would fardels bear, To grunt and sweat under a weary life, But that the dread of something after death, The undiscovered country, from whose bourn No traveller returns, puzzles the will, And makes us rather bear those ills we have Than fly to others that we know not of? Thus conscience does make cowards of us all, And thus the native hue of resolution Is sicklied o'er with the pale cast of thought, And enterprise of great pitch and moment With this regard their currents turn awry And lose the name of action. -- Soft you now, The fair Ophelia! -- Nymph, in thy orisons Be all my sins remembered.

Solution to low public transportation utilization

From Mobility for the Poor: Car-Sharing, Car Loans, and the Limits of Public Transit by Jeff Khau. An example of the importance of establishing the difference between correlation and causation; of the importance of directionality of causation; of context; of root cause analysis; and goal definition.

Theoretically, one can look at this graph and legitimately make the argument that in order to increase public utilization of public transportation, one ought to increase the average commute time. It is a good exercise in critical thinking to spot the fallacy of such an interpretation.
