It’s standard measure of acceleration. If you are going to sell a car on performance (like say… a sporty roadster), it’s a great metric.

People in the market for a car like this care far more about performance than they do safety, repairability or longevity.

That’s why performance oriented cars talk about their acceleration, and minivans talk about safety, and pickup trucks talk about longevity. Their target market determines which of the various metrics are going to be the headline.
