Here is what the page “Tesla Reverses Course on Maps, Building Own Map System for Full Self-Driving After Years o” contains. Tesla is now building its own maps to address persistent failures in its Full Self-Driving (FSD) system, including misreading speed limits, parking, and route selection. Ashok Elluswamy, Tesla’s head of AI, revealed the initiative on the company’s Q3 2026 earnings call, marking a dramatic shift from CEO Elon Musk’s long-held stance that map-dependent autonomy is brittle. For years, Tesla relied primarily on real-time camera-based perception, arguing that pre-mapped roads were unnecessary.
Now, the company’s fleet will effectively map roads to compensate for what the system cannot reliably interpret on its own. The move puts Tesla on a path similar to Waymo, which builds high-definition maps with lidar. While Tesla fans contend the approaches differ, the underlying principle is the same: both companies are creating their own maps to improve reliability.
