Tesla Inc said on Tuesday it will remove ultrasonic sensors from its vehicles starting this month, as it moves ahead with using only cameras in its safety and driver-assistant features.

Tesla vehicles now have 12 ultrasonic sensors on the front and rear bumpers, and short-range sound sensors are mainly used in parking applications and to detect close objects…

Tesla said it will remove ultrasonic sensors from the Model 3 and Model Y globally over the next few months, followed by the Model S and Model X in 2023.

The transition will temporarily limit automated parking features, but not affect crash safety ratings, Tesla noted.

“It remains to be seen whether this will be ‘two steps forward and one step backward’ or the other way around,” said Raj Rajkumar, a professor of electrical and computer engineering at Carnegie Mellon University
