Well, I thought I was quite done with the testing, but once more unto the breach... Tonight the thing decided to slow for a simple stop sign in an intersection with no other cars or pedestrians present. It stopped so slowly, and from a farther distance than I though was reasonably possible that if I had another car behind me they would have blown past and around me in a fit of rage. It was if some elderly person in a wheel chair was trying to cross the street.
Then, after a couple seconds of deciding if it was clear enough to proceed (nobody was there), it rocketed away faster than I ever have done. Note, the FSD settings were in "Chill" mode, just as my normal settings are without FSD. My DriveSafe app noted an acceleration transgression at that point, as I knew it would have, and of course, my score was reduced.
I am done. $15,000, $12,000, $10,000, $8,000... I wouldn't spend a dime on this crap.
