For a businessman who perpetually struggles with broken promises, Elon Musk has given himself quite a to-do list at Tesla’s long-awaited Hollywood unveiling of its driverless robotaxis.

After traversing the fake streets of the Warner Bros movie studio set in a sleek, silver two-door “Cybercab” prototype, Musk promised on Thursday night that the company’s popular Model 3 and Model Y vehicles would be able to operate without driver supervision in California and Texas by next year.

Musk said the company would start building the fully autonomous Cybercab by 2026 at a price of less than $30,000, and showed off a robovan capable of transporting 20 people around town – which he said would reshape cities by “turning parking lots into parks”.
