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.

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.

Waymo, the self-driving division of Google parent Alphabet, announced Wednesday it plans to bring its autonomous taxis in San Diego this year.

Waymo's autonomous vehicles are coming to San Diego — with human drivers. Why it matters: The company announced its fleet will arrive this week in San Diego and Las Vegas, where trained drivers will allow them to collect local information in hopes of improving their driverless ride-hail services.
