Tesla CEO Elon Musk first floated the idea of launching a robotaxi network using autonomous Teslas in 2019, saying he expected to begin deployment the following year. But Musk isn’t exactly known for sticking to his timelines.

Elon Musk unveiled Tesla Inc.’s highly anticipated self-driving taxi at a flashy event that was light on specifics, sending its stock sliding as investors questioned how the carmaker will achieve its ambitious goals.

Tesla plans to launch fully autonomous driving in Texas and California next year, with the Cybercab entering production by 2026 — although he said it could be as late as 2027. Additionally, Tesla is developing the Optimus robot, which could be available for $20,000–$30,000 and is capable of performing various tasks.
