The deployment of FSD on 2 million vehicles and the achievement of 1 billion miles driven are significant milestones that demonstrate Tesla's progress in autonomous driving technology. This progress, coupled with Elon Musk's emphasis on vehicle autonomy as a key driver of Tesla's market value, could positively impact investor sentiment and the stock price in the short term. However, the lack of current agreements to license FSD to other automakers and the mention of safety concerns may temper some of the positive momentum.
