NHTSA Complaint #11674749 — 2020 TESLA MODEL 3

Vehicle must have thought a shadow line in the road from a bridge indicated a wall I was about to hit, as it slammed on the breaks in the middle of the freeway. Car behind had to swerve to avoid. On the same trip, several nags of 'keep eyes on the road' were incorrect, as my eyes were directly on the road, but phone was in hand functioning as a microphone taking voice memos. Car proceeded to shut itself down while in the middle of the freeway, causing me to go slower than traffic and put me in danger as cars behind me had to swerve or lane change to avoid me as I tried to pull off to the shoulder. These forced shutdowns from incorrect 'nag fails' are causing safety issues. Nag failures should not forcibly shut the car down. Not sure if this is being enforced by NHTSA, or why Tesla is choosing to disable their auto steer or FSD when drivers are detected to be failing nags - nags should be there to help drivers, and potentially the nag data/cab video can be used after the fact should a user failing nags be involved in an accident for insurance dispute resolution, but shutting the cars down themselves is causing issues.
