Tesla shareholders are eager for updates on product delivery timelines, with top-voted queries focusing on new models, the next-gen Roadster, and the Semi truck. Tesla’s history of delayed promises has driven these questions, especially as the company’s full self-driving technology faces delays. Tesla CEO Elon Musk explained that he bases his predictions on the 50% percentile, leading to half being late and half early, but claims the press focuses only on the delays. Musk's 2015 prediction of achieving full autonomy by 2018 has not been realized, raising doubts among customers and shareholders about Tesla's upcoming plans for affordable models and autonomous rides.
