Tesla's stock experienced significant fluctuations over the weekend, initially dropping on reports of scrapped plans for a low-cost electric vehicle (EV), but later rallying after CEO Elon Musk denied these reports. The stock saw a further increase after Musk announced plans to unveil a robotaxi on August 8. This announcement has sparked a wide range of reactions, with some analysts warning that Tesla's shares could still fall significantly, while others view the move towards robotaxis as a risky bet due to technological and regulatory hurdles. Despite these concerns, the robotaxi announcement has led to a 3.9% increase in Tesla's stock in premarket trading. The shift towards robotaxis has been seen as a potential game-changer for the automotive industry, with predictions that other major automotive companies will follow Tesla's lead. The announcement comes amid Tesla's preparation for a high-profile trial over a fatal crash blamed on its Autopilot system in 2018, highlighting the challenges the company faces in its pursuit of autonomous driving technology.
