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.

Waymo will test their self-driving cars this summer in Philadelphia and New York as the company preps for further expansion of its rideshare services.

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.
