While Tesla focuses on its robotaxi launch, Rivian is looking to take hands off the wheel and eyes off the road while enabling drivers to chat with the car.

While the initial testing will use Tesla's own fleet of cars, regular customers may be able to add their cars to the ride-hailing fleet next year, Musk says.

Tesla reported disappointing fourth-quarter earnings for 2024, with revenue of $25.7billion (£20.6billion) falling short of Wall Street analysts' predictions of $27.2billion (£21.8billion). The electric vehicle maker's shares dropped approximately four per cent in after-hours trading following the announcement on Wednesday.
