Waymo, the autonomous driving technology company, is bringing a fleet of testing vehicles to Philadelphia this year. "This city is a National Treasure," Waymo wrote on X. "It's a city of love, where eagles fly with a gritty spirit and cheese that spreads and cheese that steaks.

Waymo is launching a new account type that lets teenagers hail a robotaxi and ride alone, expanding its rider base while continuing to test its service in more US cities.

Once a teen account is activated, young riders can hail fully autonomous rides across Waymo's local operating area, which covers 315 square miles of the Valley.
