You can reset your safety score by un-enrolling, wait a about 4 hours, enroll again and drive 100 miles. At the end of the 100 miles if you have a 99 or 100 score you will get an email within a few hours saying you can enable FSD. I did this when I had an initial score of 96 (I live in NYC so I’m lucky to have had that high of a score.). This was a month ago, since then I dealt with NYC traffic and no issues with FSD getting revoked.
