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.

Waymo has begun offering teen accounts for families in Phoenix as it works to expand more of its user base and entrench young riders in the autonomous life.
