Tesla boss Elon Musk is to unveil the firm's long-awaited robotaxi prototype, the Cybercab, at the Warner Bros Studios in Burbank, California on Thursday.
Self-driving cars have long fascinated Mr Musk and he has made a series of bold predictions about them - including that they will save lives or earn their owners money, through being rented out for rides or even overnight stays.
But when he takes to the stage for the event - which the company has billed We, Robot - he will be under pressure to quell persistent doubts about the electric vehicle maker's ability to execute on his ambitions.
The project has undergone delays, having been originally slated, external for release in August before being moved to October.
"Requested what I think is an important design change to the front, and extra time allows us to show off a few other things," Musk wrote, external in a July post on his social media platform X.
'There is certainly heavy build-up after discussing the Robotaxi concept without concrete details for so long," said Jessica Caldwell of edmunds.com.
