But the system has a leg up on its human competition.

Safer System

On Wednesday, Tesla released its third quarter 2019 update, and the good news wasn't limited to the company's buoyant financials.

According to Tesla, cars with Autopilot engaged were involved in one accident for every 4.34 million miles driven during the quarter. The average for human drivers in the United States is one accident for every half million miles — making Autopilot nine times less likely, according to the Elon Musk-led automaker, to be involved in an accident.

Autopilot Advantage

Tesla pulled its figures on human-driven cars from National Highway Traffic Safety Administration (NHTSA) data, but as pointed out by Electrek, the company isn't exactly comparing apples to apples.

Autopilot is typically used on highways, for example, where driving conditions are simpler than surface streets. And Teslas are generally newer vehicles, giving them a leg up in terms of safety when compared to the range of other, sometimes much older vehicles contributing to the accidents recorded by the NHTSA.

Autopilot arguably has another advantage, too: if a Tesla with Autopilot engaged makes a mistake, the human driver can quickly take over the controls to avoid catastrophe.

Level Playing Field

A more apt comparison might be Autopilot to previous versions of itself — and there's good news there, too.

In the first and second quarters of 2019, the system's accident rate was approximately one accident for every 2.87 million miles and 3.27 million miles, respectively — making the jump to 4.34 million impressive even when human-driven cars are removed from the equation.
