According to Sawyer Merritt, Tesla's newly built Model Y Robotaxis in Austin feature three significant hardware upgrades over previous models: a rear camera washer, side repeater camera washers, and enhanced front camera housing with black lines likely for improved sealing. These AI-driven changes are designed to ensure camera cleanliness and reliability, directly improving the performance and safety of Tesla’s Full Self-Driving (FSD) system (source: Sawyer Merritt on Twitter). The integration of dedicated washers addresses a key challenge in autonomous vehicle deployment—sensor obstruction—offering a tangible business opportunity for further AI-enabled sensor maintenance technology and setting a new industry benchmark for robotaxi fleets.
