12-5-2017, Los Angeles — The traffic on California freeways outside the Los Angeles Convention Center is relentless. So it’s fitting that automakers are thinking big at the Los Angeles Auto Show about autonomous cars that relieve driving stress.

But while the industry agrees on an autonomous, self-driving future, the paths that automakers are taking to get there vary from Audi to Tesla to General Motors to Toyota.

Audi made headlines this week with the U.S. introduction of its flagship A8 sedan with Traffic Jam Assist, the first so-called Level 3 autonomous system that lets the car take full control from the pilot. It will drive itself under 37 mph, allowing drivers to disengage from the car to check email, text and engage in other distractions.

Cadillac debuted its similar “SuperCruise” system this fall on the brand’s flagship CT6 sedan. It will also be hands-free, but is considered a Level 2 system because its still requires driver attention on a defined network of divided, limited-access highways. GM’s Chevy division is testing a fleet of autonomous Bolt EVs equipped with LIDAR sensors that allow fully-autonomous, Level 4 capability.

And then there’s Toyota. In contrast to America’s colossus GM, the Japanese giant has kept a low profile. But with the LA show it’s starting to show its hand.

Lexus, Toyota’s premium brand, introduced the latest version of its Lexus Safety Sense system, LSS+A, on Tuesday to the media. Building on previous systems that automatically brake to mitigate impact with other vehicles or pedestrians, LSS+A takes a big step toward autonomy by steering and braking to a stop to avoid impact. The Level 4-like feature only works when the driver is disengaged.

“They are creating a path to much more advanced autonomous-driving technology,” says Kelley Blue Book analyst Karl Brauer.

He’s referring to the confluence of two Toyota autonomy streams by 2020: Toyota’s “Mobility Teammate” hands-free driving system for consumer cars and a fully autonomous ride-sharing service for the 2020 Tokyo Olympic Games for which Toyota is the exclusive transportation partner.
