Waymo begins autonomous taxi service to SFO airport

Waymo has long served Sky Harbor airport in Phoenix, and the smaller SJC airport in San Jose, but SFO is another beast.

Waymo is finally starting passenger trips at SFO — but not to the terminals

But Waymo won’t have unfettered access to SFO’s terminals, at least not this year. Pickups and drop-offs will take place at SFO’s Rental Car Center, which is accessible to the terminals via the AirTrain. Additional locations, like the airport’s main terminals, will come later.
