Investor Ross Gerber of Gerber Kawasaki recently highlighted potential limitations of Tesla's Full Self-Driving (FSD) v14.2.1.25 system, specifically its functionality during rainfall. His observations emerged as industry experts have otherwise lauded the FSD v14's advancements. Meanwhile, Tesla CEO Elon Musk has publicly affirmed significant strides in the company's autonomous driving capabilities, even claiming to have been driven autonomously in a Tesla Robotaxi in Austin without a safety monitor.
Investor Raises Concerns Over Tesla FSD v14 Performance in Inclement Weather
On Wednesday, December 26, 2025, investor Ross Gerber, a co-founder of Gerber Kawasaki, took to social media platform X to share his recent experience with Tesla's Full Self-Driving (FSD) system. While testing the FSD 14.2.1.25 update on his Cybertruck during a rainy outing, Gerber encountered a notable issue. The FSD system displayed a 'Autopilot Visibility Limited' prompt, advising the driver to clear debris from the camera. However, Gerber noted, "There is no dirt. It's just rain," suggesting that the system was misinterpreting raindrops as obstructions. This incident prompts further inquiry into the FSD's robustness in adverse weather conditions. His recent experience contrasts with his earlier positive assessment of the FSD v14 update's overall improvements. Concurrently, Tesla's CEO, Elon Musk, has been vocal about the progress of the company's autonomous technology. He recently reported being driven autonomously around Austin by a Tesla Robotaxi, emphasizing the absence of a safety monitor during the ride. This claim aligns with Musk's stated goal of deploying driverless operations in Austin by the end of the year, a target that has been supported by recent sightings of Tesla Robotaxis operating autonomously in the city.
The disparity between these firsthand accounts highlights the ongoing challenges and rapid developments in autonomous vehicle technology. While the FSD system shows promise and receives high praise for its advancements, its performance in varied real-world conditions, such as rain, remains a critical area for further refinement and public assessment. This underscores the need for continued rigorous testing and transparent reporting of autonomous driving systems' capabilities and limitations.
