Driverless rideshare service Waymo, owned by Google parent Alphabet, deployed its fleet to New York City this week to begin mapping out the city roads – with humans still sitting behind the wheel while they await a change in state law to allow fully driverless riding.

Waymo kicked off two “road trips” to Philadelphia and New York City on Monday, signaling the Alphabet-owned company’s push to expand into cities in the Northeast.

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.
