Tesla has patented previously unused technology.
A novelty will be the laser cleaning of the windshield with solar panels. In practice, all foreign elements will be removed due to the laser.
A file published by the US Patent and Trademark Office describes the principle of the technology: the special sensors fix the debris on the glass with the car body, and then the lasers remove unwanted elements with rays.
The lasers' power is regulated in such a way so as not to harm passengers with others. At the same time, sensors will distinguish unwanted debris from stickers and sun visors.
