Wall Street Analyst Claims Tesla Has Achieved “Level 4” Self-Driving

A Wall Street analyst from Piper Sandler, Alexander Potter, has asserted that Tesla’s Full Self-Driving (FSD) system has effectively reached Level 4 autonomy in most conditions. This claim marks a significant shift in the ongoing debate over Tesla’s autonomous driving capabilities, which have steadily improved over recent years but remain officially classified as “supervised.” Potter bases his view on several indicators, including Tesla’s decision to offer lower insurance premiums to frequent FSD users, the launch of volume production for the Cybercab robotaxi, and Tesla’s active pursuit of permits to expand its robotaxi service in locations such as Irving, Texas. Potter also highlights Tesla’s recent transparency in sharing FSD subscription data, a move that suggests the company believes the technology is ready for wider adoption beyond early enthusiasts. Tesla aims to extend its robotaxi service to seven additional cities within the first half of 2026, although Potter acknowledges this timeline may be ambitious. Drawing from personal experience, Potter recounted a long-distance drive using FSD without needing to intervene, underscoring the system’s growing reliability under favourable conditions. Despite these positive signals, scepticism remains strong among critics who point to Tesla’s ongoing limitations. The system reportedly struggles in adverse weather and complex urban environments, and there are concerns about driver complacency given the need for supervision in edge cases. Furthermore, crash data from Tesla’s limited robotaxi deployment in Austin has not been encouraging, and the company has yet to assume liability for accidents occurring while FSD is engaged. Tesla’s cautious rollout and the disparity between supervised and fully autonomous performance statistics continue to fuel debate about the true readiness of FSD. The broader implications of Potter’s assessment could be significant for Tesla’s autonomous ambitions and the wider self-driving industry. If Tesla’s FSD is indeed approaching Level 4 autonomy, it may accelerate regulatory approvals and consumer acceptance, potentially transforming urban mobility through robotaxi services. However, the gap between technological promise and real-world performance remains critical, and the risk of overestimating FSD’s capabilities could have serious safety consequences. The coming months will be pivotal in determining whether Tesla can fulfil its vision of widespread, reliable autonomous driving.
