There’s a general requirement that crashes have to be reported to NHTSA if a Level 2 (or higher) ADAS was engaged up to 30 seconds prior to the event - but not whether Tesla counts them as FSD accidents or manual accidents. NHTSA only requires they be reported, not that the automaker treat them any particular way.
Like Goofy, I couldn’t find anything that confirmed how Tesla classifies those types of incidents. Do you have a link?
