Tesla CEO Elon Musk has repeatedly missed his own robotaxi and autonomy timelines, according to a Motley Fool article published on August 1, 2026. In 2013, Musk said Tesla "should be able to do 90% of miles driven [autonomously] within three years," and in 2015 he predicted "complete autonomy in approximately two years." He later said in 2023 that full autonomy "is gonna happen this year," and in 2025 claimed the ability to "go to sleep in your car and wake up in your destination" would be available in many U.S. cities by year-end, also declaring there would be "no safety driver by the end of the year" for Tesla's robotaxi service in Texas. None of these predictions came to pass. Despite this, Ark Invest CEO Cathie Wood has bought 160,000 shares worth approximately $50 million following a recent drop in Tesla's stock, which has fallen by roughly 30% since the start of 2026. Wood's thesis relies heavily on Tesla's robotaxi division, predicting the global robotaxi market will be worth between $8 trillion and $10 trillion over the long term, and that Tesla's stock price will reach $2,500 by 2030, with the robotaxi division accounting for around 90% of that value.
