I agree with this if you amend it to &quot;... they believe it is much ...&quot;<p>It is usually faster (some metros excepted) and usually more reliable, but people seem to consistently underestimate how much they spend on their cars.  If you live in a major metro area (not its suburbs) my guess is that public transit is usually much cheaper.  It certainly is in the ones I have lived in.  If you&#x27;ve got a decent transit system (and that&#x27;s a big if in North America), of course.<p>On the other hand, there are plenty of living arrangements that make transit impractical.
