I opted out and opted back in this week. Used the reset feature to keep my score at 100 (impossible to do it any other way in city driving).
- Opted back in Monday the 25th
- Drove carefully Mon-Thurs - 203 miles on the Safety Score
- Kept Safety Score at 100, reset the car any time someone cut in front of me or I feared something else like hard breaking might be detected. I did this probably 1 out of 3 trips or more, and am convinced it works as reported
- Plugged the car in last night (4th day of Safety Score) and connected it to WiFi
- Received email this morning (5th day of Safety Score) to download FSD
Hope this helps anyone trying to get the FSD Beta
