Tesla will give three months of Full Self-Driving free to all cars delivered in the final three days of 2020, with delivery and paperwork complete by midnight Dec 31.

True: Tesla gave three months of Full Self-Driving free to buyers whose deliveries were completed on 29 to 31 December 2020, shown by owner reports, Tesla communications, or FSD trial or subscription access appearing on those cars. Mostly true: the offer was honoured, with a minor difference such as the exact length of time or some delay in turning it on. Mixed: it was applied to some qualifying buyers but not to others. Mostly false: something much smaller was given instead. False: there is evidence that qualifying buyers did not receive it, or that Tesla withdrew the offer.

5. E5 FSD will be free for 3 months if you buy a Tesla in the last 3 days of 2020 techau.com.au · 30 December 2020

   “To clarify, this offer was only made in specific markets, which unfortunately did not include Australia.”

The independent reports (E1, E4, E5) confirm that the offer was announced on 29 December 2020. None of them reports whether buyers who took delivery between 29 and 31 December actually got three months of FSD access. MotorTrend (E3) says Tesla had given no details beyond Musk's tweet. Techau (E6) says the offer was limited to certain markets, which limits who could qualify but does not show that qualifying buyers went without it. No owner reports, Tesla communications or records of trial activation are in the evidence, so whether the offer was honoured cannot be determined.
