I have used FSD for approximately four years and have extensive experience with the system. During several recent road trips through heavily forested and mountainous areas, including Yosemite National Park and multiple locations throughout Oregon, I repeatedly observed similar unexpected behavior under the same environmental conditions.  On roads where dense tree cover creates alternating bands of sunlight and shadow across the pavement, the vehicle occasionally performs abrupt deceleration, unnecessary braking, or jerky speed adjustments despite there being no visible hazards, obstacles, pedestrians, or animals in the roadway.  I cannot determine the technical cause, but based on repeated observations at different locations, it appears that rapidly changing lighting conditions or high-contrast tree shadows may present a perception challenge for the vision-based driving system. This is only my observation and not a technical conclusion.  My concern is that unexpected braking or sudden speed changes could surprise following drivers and increase the risk of rear-end collisions, particularly on two-lane highways or winding mountain roads. While I remained attentive and was able to supervise the vehicle, these unexpected reactions occurred multiple times under similar conditions.  I respectfully request that NHTSA evaluate this type of real-world driving environment as part of its ongoing assessment of advanced driver assistance and automated driving systems. Forested roads and mountain highways are common throughout the United States, and ensuring reliable performance in these challenging lighting conditions is important before wider deployment of autonomous driving technology.  I would be happy to provide additional information if needed.","products":[{"type":"Vehicle","productYear":"2023","productMake":"TESLA","productModel":"MODEL Y","manufacturer":"Tesla, Inc."}]}]}
