Tesla to ditch radar sensors and rely on Autopilots in some models

American electric vehicles and battery maker Tesla will drop the radar sensor technology in favor of a camera-focused Autopilot system for its Model 3 and Model Y vehicles in North America from this month.

The move came amid growing scrutiny by regulators and media about the safety of what Tesla dubs “Autopilot” and “Full Self-Driving” (FSD) features, following a series of crashes.

“Pure vision Autopilot is now rolling out in North America,” CEO Elon Musk said in a Tweet. He said it plans to release an improved “FSD beta V9.0” based on the pure vision system about three weeks later. “FSD subscription will be enabled around the same time,” he added.


According to the company’s website, Autopilot currently enables a Tesla vehicle to “steer, accelerate and brake automatically within its lane” and FSD adds features such as automatic lane changing and summon. Summon enables a driver to call their car to come pick them up across a parking lot using the Tesla app like a remote control.

The company said these will be the first Tesla vehicles to rely on camera vision and neural net processing to deliver “Autopilot, Full-Self Driving and certain active safety features.” In October, Tesla rolled out the test version of its new FSD system to a limited number of people, enabling cars to navigate on city streets in semi-autonomous mode as well as highways. A wider launch has been delayed.

Safety concerns

While most companies like Alphabet’s autonomous vehicle company Waymo equip their cars with cameras paired with sensors like lidars and radars, Tesla relied on cameras and one radar to detect and analyze objects. Tesla’s approach helped reduce costs and commercialize its driver assistant features, but experts and other companies have raised safety concerns.

Tesla said the transition to a camera-focused system may result in limitations of some features such as lane-centering and parking assistance, saying those functions will be restored via software updates “in the weeks ahead.” All new Model S and Model X cars, as well as all vehicles built for markets outside North America, will still be equipped with a radar, Tesla confirmed.

In March, the electric vehicle pioneer told regulators in California it might not achieve full self-driving technology by the end of 2021, as claimed earlier.
