Musk has come up with a tried and tested trick: to change the market atmosphere with the vision of a new product. Musk has mastered the art of making investors focus on the future rather than the current pain points, yet it usually takes years for Tesla to turn the products Musk has drawn into reality. As for driverless taxis, Musk's predictions about autonomous vehicles more than 10 years ago have not been fulfilled. “Investors need to restrain their enthusiasm about this stock and its various product announcements, as there is often a huge gap between hype, speculation and reality,” Adam Crisafulli, founder of analytics firm Vital Knowledge, said via email. “This seems like an example of Tesla trying to divert attention from the very bleak electric car market.”
