Last week, I spent $102 to get my car fixed. Or, more accurately, I spent $102 to replace two faulty tire-pressure sensors that had triggered an ominous-looking amber dashboard light. The light erroneously indicated that one or more of my tires was dangerously low.
My tires were fine.
Perhaps you are familiar with that warning light: It’s a sort of horseshoe shape with the ends pointing up. It’s ripply on the bottom, with an exclamation point in the middle, meaning “Hey, pay attention, this is super important!”
