THE BODY

The combination of hardware, software, and manufacturing that forms a driverless vehicle.

HOW IT WORKS Some autonomous vehicles might require zero driver input, while others will need some variation of human decision making (see “Achieving SelfDriving Nirvana,” opposite page).

COMPETITORS More than 16 startups, including Faraday Future, backed by Chinese billionaire Jia Yueting, and Lucid Motors, a manufacturer of electric cars with automated driving features—both angling to take on Tesla. Meanwhile, Zoox is developing a fully autonomous urban car fleet.
