Tesla Inc (NASDAQ:TSLA) said that it is working hard to “improve autonomous safety features and make self-driving a reality. To achieve its goals, the electric car maker needs data and information. Recently, the company updated its policy to include the collection of footages to help to improve its self-driving technology, according to a report from Electrek.

Tesla’s second generation Autopilot has eight cameras, all-around ultrasonic sensors, and a forward-looking radar to detect people and obstacles as well as to see road markings, street signs, and traffic lights.

“We need to collect short video clips using the car’s external cameras to learn how to recognize things like lane lines, street signs, and traffic light positions. The more fleet learning of road conditions we are able to do, the better your Tesla’s self-driving ability will become,” according to a statement from Tesla quoted by Electrek.

According to Tesla Inc (NASDAQ:TSLA), it will share some of the data with partners. But the company assures its customers that there is no risk to their privacy.

“We want to be super clear that these short video clips are not linked to your vehicle identification number. In order to protect your privacy, we have ensured that there is no way to search our system for clips that are associated with a specific car,” the company said.

“In order for these features to work, Tesla measures the road segment data of all participating vehicles but in a way that does not identify you or your car, and may share that with partners that contribute similar data to help us provide the service. At no point is any personally identifiable information collected or shared during the process.”
