Uber is investing hundreds of millions of dollars into Lucid and autonomous vehicle technology startup Nuro in a bid to launch its own robotaxi service.

The partnership will combine Uber's ride-sharing platform with Lucid's new electric SUV, the Gravity, and Nuro's autonomous driving technology. It'll be launching first in an unnamed "major US city," but is expected to roll out globally to more than 20,000 Lucid vehicles over the next six years.
