Elon Musk reposted a tweet from Sawyer Merritt, who stated that FSD has become a major driver of Tesla's sales growth in North America. Merritt suggested that people might be underestimating FSD's boost to Tesla's sales, as many first-time Tesla buyers now cite FSD as their primary reason for purchase, which was not the case earlier this year. He noted a real shift in public perception of the technology over the past 3 to 6 months.
