For about two weeks, residents of the 500 block of Seventh Avenue in San Bruno's Belle Air Park say driverless Waymos have been dropping SFO-bound passengers on their street with luggage and idling across driveways. One neighbor counted 29 in a day. The account rests on one outlet; the route that explains it checks out against Waymo's own record.

The 500 block of Seventh Avenue, in San Bruno's Belle Air Park, is a street of single-family homes with driveways and parked cars — the kind of block where the loudest thing most mornings is a garage door going up. For about two weeks now, residents say, it has been standing in for the drop-off curb at an international airport it can't see.

The account comes from a single place: a July 30 segment by NBC Bay Area reporter Alyssa Goard, who spoke with six neighbors. No other outlet has been on the block. But the one part that can be checked independently — Waymo's route to SFO — holds up, and it helps explain why the cars keep choosing this street.

Neighbors told the station that driverless Waymos have been pulling up and letting out passengers bound for San Francisco International, three miles and roughly ten minutes north. Riders step onto the sidewalk with their suitcases, several residents said, and stand there working out how to finish a trip the car has decided is over. Robert Riechel, who says he has lived in the neighborhood twenty years, said he talked to a number of them — one man headed to Switzerland; another, with three rolling suitcases, said he was just going to walk, which from that block means at least twenty minutes down busy San Bruno Avenue. City leaders told NBC that Seventh Avenue is the residential street closest to the airport, which appears to be exactly the problem.

The volume is what turned an oddity into a complaint. One neighbor counted 29 Waymos on a single Sunday; by Thursday the count was five. Cars also idled long enough to block driveways, residents said. San Bruno police confirmed officers were called to the block twice, and that one spoke with a Waymo representative on the street Thursday. Council Member Marty Medina, who represents the area, said he has emailed the company about the parking and drop-offs and is trying to schedule a call, floating vacant city lots as an alternative.

Why the block at all traces to how Waymo reaches SFO. When the company launched airport service on January 29, its own announcement said pickups and drop-offs would happen only at the SFO Rental Car Center, reached by a short AirTrain ride, "with plans to serve additional airport locations like the terminals in the future." A Waymo spokesperson now tells riders they can also be let out at the Grand Hyatt — still an AirTrain transfer to the gate, unlike San Jose's Mineta airport, where the cars pull up across from the terminal. Thursday night the spokesperson said that after rider feedback the company had "been able to remedy the situation." What a neighbor on Seventh Avenue notices tomorrow is simpler than a statement: whether the cars come back, and whether the next stranger with a suitcase turns up on the sidewalk.
