Waymo, the California-based autonomous vehicle company, has brought a limited fleet of vehicles piloted by trained, human autonomous specialists to test on Las Vegas roads, company officials

Waymo is sending autonomous vehicles to 10 new cities in 2025, starting with Las Vegas and San Diego, the company shared exclusively with The Verge. The vehicles will be manually driven, and the testing operations are not necessarily a precursor to the launch of a commercial robotaxi service.

Shares of Uber and Lyft fell Wednesday amid a report Alphabet's Waymo plans to expand autonomous vehicle operations to 10 more cities in 2025.

The cars will be trying to navigate unfamiliar streets in San Diego and Las Vegas to begin with, then make the trip to at least eight other cities.
