Waymo, the autonomous driving technology company, is bringing a fleet of testing vehicles to Philadelphia this year.

If you're driving or walking around Philadelphia in the next few weeks, you could see one of these Waymo driverless taxis. Philadelphia is one of several cities where the cars will be on the streets.

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.
