Betrayed by our car, we come up against all the things we don’t know. Is it time for a new vehicle? Did I err in my original purchase? Is the mechanic competent, honest and reliable? Is the garage he works for trustworthy? Sometimes, too, we must contemplate something worse, something broader and deeper: Have the roads now become too dangerous? Have I become (or always been) too incompetent? Too scattered and inattentive? Too old?
