User reports FSD 14.3.8 swung toward construction barrels on a left turn

Unconfirmed: a Reddit user describes an incident that occurred about a month ago with a 2026 Model Y (HW4) running FSD version 14.3.8. While making a left turn to enter a highway on-ramp, the vehicle swung right toward traffic barrels and dirt on the shoulder. The driver says he intervened manually, braking and steering back left to avoid the impact. According to the author, he uses FSD about 98–99% of the time, with over 5,000 miles logged, and weather and lighting conditions were good. The post also mentions a similar case shared by others, but the text cuts off before citing it.
