Not long ago, the Tesla Model S P100D was announced as one of the fastest-accelerating production cars on the planet, taking 2.5sec to reach 62mph.

Five minutes or so passed, and Faraday Future announced that the FF 91 – not yet a production car, but it will be soon, the firm said – undercut the Tesla by 11 hundredths of a second at 2.39sec.

Tesla has now responded, albeit indirectly, by claiming that in a certain spec, the P100D could actually accelerate to 62mph in 2.34sec.

On the surface, it’s petty, but this masks a more serious point; that the de facto single decimal-place system for measuring 0-62mph times is now out of date. Things, literally, are moving so fast that they’re ageing our measurement system.
