The price reduction of Tesla's FSD package to $99 could have a mixed impact on TSLA's stock in the short term. On one hand, it could boost subscription numbers and user engagement with Tesla's technology, potentially increasing recurring revenue. On the other hand, it contradicts Elon Musk's previous statements about increasing FSD prices, which could raise concerns about the company's pricing strategy and future revenue projections from FSD. Additionally, the backdrop of legal controversies and the significant milestone of one billion miles driven using FSD software add complexity to the potential impact on the stock.
