Philadelphia is one of more than 10 cities where human autonomous-technology experts will be taking Waymos on summer “road trips,” allowing the cars “to get to know the city,” spokesperson Sandy Karp said in a statement. The testing fleets are closed to the public.

The autonomous vehicle company says it will have a fleet in the city this summer, but the cars won't be available for ride-hailing.

State of play: Waymo began deploying a fleet of cars with a human driver in Philly this week. Yes, but: You can't hail one. The fleet is closed to the public as the company develops its autonomous driving technology and familiarizes itself with the city.
