> If your car won’t start, it will take more than a second, but less than a year to fix. That is a bad estimate

It's actually a better estimate than most software estimstes, because it isn't just an expected time but a range that results will usually fall within. It would be better if it included an explicit degree of confidence that th actual result would be in the range, and if it was centered around the average time it would take for events in the class.
