Current Challenges (3-17-2025)
Camera Obstruction
A primary challenge encountered by FSD systems is the obstruction of cameras due to environmental factors such as rain, snow, fog, and debris. When driving in heavy downpours, for instance today, I encountered FSD issued warnings that “camera is blocked or blinded” during the highway driving. which led to deactivation of autonomous functionalities. This issue arises from the inability of cameras to effectively capture clear images under such conditions, thereby compromising the system’s ability to analyze surroundings accurately.
Sensor Limitations
FSD systems rely heavily on a combination of sensors, including cameras, LiDAR, radar, and ultrasonic sensors, to navigate and make decisions. Rain can scatter LiDAR signals, fog can diminish radar effectiveness, and snow can obscure ultrasonic sensors. These limitations hinder the system’s ability to maintain a consistent and accurate understanding of the vehicle’s environment.
Software Adaptability
Another critical challenge is the adaptability of the FSD software to changing weather conditions. Current algorithms may not be sufficiently robust to handle the variability introduced by adverse weather. For example, the system may struggle to differentiate between wet road surfaces and icy patches or misinterpret reflections caused by rain. This lack of adaptability can result in incorrect or delayed responses, jeopardizing the safety and efficiency of autonomous driving.
