When a Waymo pulls up and parks in entrance of her residence on a residential avenue in West Los Angeles, 10-year-old Morgan rushes to the window.
“The Waymo is residence!” she says, calling to her mother and father, Lisa Delgin and Zach Tucker.
It’s certainly not the primary time a Waymo has come “residence” to this explicit spot. Final yr, a Waymo robotaxi dropped Delgin and Tucker off after a New Yr’s Eve get together and idled there for a number of minutes till it took off for the following trip. Since then, Waymos have been parking in that very same spot, day after day, typically for minutes, typically for hours.
“It could at all times come again right here, like a beacon,” Delgin stated. “Prefer it knew there was a spot right here that it may take.”
As with Uber rideshares and Chook scooters earlier than them, Waymos are the newest tech transportation innovation to begin displaying up in individuals’s lives — and so they typically trigger friction with residents within the cities that grow to be their first markets.
However the AI of all of it provides a layer of opacity to those interactions. Confused driverless vehicles appear to make random stops, their necessary backup sounds are irritating, and it’s unclear whether or not they’re even beholden to visitors legal guidelines, human drivers allege. On the subject of parking in neighborhood spots, some residents are aggravated, and a few are unsettled by the always-on cameras and sensors. However most simply wish to know why their properties or blocks appear to have grow to be unofficial Waymo hubs.
“Of all of the blocks…” Delgin wonders. Why hers?

Morgan, for her half, is delighted by the Waymo’s return visits, since she sees it as approval of their household by the robotic vehicles. Her mother and father have been extra curious, so that they’ve run some casual experiments.
They’ve realized that it’s not only one Waymo taking the spot, since Tucker has documented the license plates of a number of totally different autos. A Waymo may even solely choose considered one of two particular parking spots: instantly in entrance of their residence or straddling the property line with their neighbors to the south. Delgin has seen that if each of these two spots are taken, a Waymo coming by way of will decelerate, however not cease or attempt to park elsewhere on the road, even for open spots instantly in entrance of, behind, or throughout the road from their residence.
The Delgin / Tucker household shouldn’t be alone in noticing the repeated presence of a parked Waymo in LA, the place the robotaxis have operated since November 2024. A resident of the Pico / Fairfax neighborhood, Tal (who most popular to be recognized by her first identify), stated a Waymo usually parks on her avenue, at all times in entrance of an condominium constructing a number of doorways down. The Verge has noticed a Waymo often on the similar location on a avenue in Brentwood. A number of customers on Nextdoor have requested fellow neighbors (or complained) in regards to the phenomenon in neighborhoods throughout LA, together with Palms, Playa del Rey, and Westchester.

The observe has additionally been ongoing in Arizona, the place Waymo has operated since 2020. One Scottsdale household says a Waymo usually parks across the nook from their residence, which is adjoining to a shopping mall. In current months, Reddit customers in Phoenix have documented the robotaxis’ frequent spots, whereas a 2023 AZCentral article first documented the phenomenon. “How do you cease Waymo from storing vehicles in entrance of your own home between journeys?” asks one Reddit thread.
Whether or not a human or AI drives a taxi, it is smart {that a} automobile would idle for a while earlier than it’s dispatched on its subsequent trip. However what makes Lisa Delgin’s residence or the Pico / Fairfax constructing a secure haven for the robotaxis, with such obvious specificity? Neighbors have their theories: proximity to high-traffic areas, central places, an absence of parking restrictions, ample curb house. However none of that accounts for the repeated specificity of the parking selection.
And sadly, not even Waymo the corporate essentially totally is aware of the reply.
Can a robotic catch a break?
The place does a Waymo go on its downtime? The corporate acknowledges that avenue parking could also be part of a Waymo’s day by day routine. There are parking depots all through LA the place Waymos get charged and cleaned. However when not in use, the corporate says that the vehicles park outdoors the Waymo heaps, too.
“Our autos will discover acceptable parking spots to attend for brief durations between journeys, both in Waymo’s parking services or on-street parking places,” Vishay Nihalani, Waymo’s director of product administration, stated in an announcement. Waymo is even collaborating in a forthcoming research from UC Berkeley and UC Irvine analyzing avenue parking conduct, and its affect on trip wait occasions and curb and highway congestion, by offering researchers with mixture / hypothetical information.
Waymo avenue parking conduct differs from a cab or different rideshare automobile. After the morning rush, Uber driver / actor Josh Myra heads residence, which is of course the place he parks his automobile when he’s not taking rides. In any other case, Myra doesn’t make a observe of parking in residential neighborhoods between rides. When he’s not working, he’s parked at residence. And if he’s on the lookout for rides, he’ll normally drive round high-traffic areas, a observe often called “deadheading,” since he will get way more trip requests when he’s in movement versus when he’s stopped. Myra stated that is typical of many of the Uber drivers he is aware of.
But when a Waymo isn’t at a depot, or doesn’t want to go to a depot for a cost or service, it’s not essentially going to behave like an Uber driver and chase rides. If Waymo isn’t seeing a excessive quantity of visitors for trip requests, it could select to park to preserve vitality and keep away from contributing to visitors, whereas additionally making certain there’s some Waymo protection in non-high-traffic zones.
“When Waymo autos are idle and don’t have charging or upkeep wants, they select between parking in close by spots or driving to areas of excessive demand,” Nihalani stated. The Waymos decide to drive to those “high-demand” areas when “they’re more likely to rapidly obtain the following hail.” If high-demand areas have an enough variety of Waymos close by, the vehicles could select to park. “This permits us to finest match ride-hailing demand and automobile provide, whereas conserving vitality and lowering visitors congestion,” Nihalani stated.
As for the place to drag over, there are some things that definitively go into Waymo’s parking selections. First is “native parking laws,” so that features the precise curb restrictions akin to cut-off dates or avenue sweeping. Subsequent is “the variety of our autos which might be parked in a given space.” If there are already Waymo autos servicing that neighborhood, the person Waymo is more likely to transfer on. And at last, “how lengthy they continue to be parked.” If they have an inclination to hang around there for lengthy durations of time, that would imply a Waymo may not park in that neighborhood (or spot) sooner or later, because it signifies there’s not a lot demand in that space.
The choice to park or head to a depot or a heavy-traffic zone seems to be a balancing act. If a neighborhood doesn’t have one other Waymo close by, and high-traffic areas are saturated with Waymos, parking in a spot with minimal curb restrictions could be the only option. The curb visitors research helps this: UC Irvine lead researcher on the curb research Michael Hyland stated information confirmed that avenue parking reduces wait occasions and highway congestion. Though it does, clearly, take up extra parking spots.

Whereas Waymo supplies basic perception into its parking selections, it doesn’t tackle the specificity of the locations its autos select to cease — in entrance of the identical home or condominium constructing, over and over.
Waymo acknowledges the particular repeat parking phenomenon, however says that the vehicles’ AI is making so many dynamic choices in driving in addition to parking — about security, accessibility, and congestion — that it may’t say why a Waymo selects a spot for idling or parking.
Neither the repetition nor the shortage of readability across the conduct shock Phil Koopman, a Carnegie Mellon professor and autonomous automobile professional. “A pc simply doing precisely the identical factor the identical means each time shouldn’t be a shock to anybody,” Koopman stated. “That’s how computer systems are.” Primarily, they’re sensible sufficient to seek out a completely optimized parking spot — however not essentially elastic sufficient on this occasion to decide on a close-by spot if the optimum spot shouldn’t be out there, the best way a human would.
As for a way the computer systems are arriving at that end result, Koopman has one other principle. Waymo saying that solely the automobile’s laptop actually is aware of why it does what it does leads him to imagine that Waymo is utilizing machine studying to direct its curb parking choices. Machine studying signifies that Waymo engineers present the vehicles with information that enables them to make their very own choices primarily based on that information, quite than present particular directions by way of a human-written algorithm.
“Machine studying appears to be like at statistical info and comes up with a solution, and no one has any thought the way it obtained there,” Koopman stated. “And plainly they’re presently not optimizing to range the placement for no matter purpose.”
Waymo doesn’t verify or deny its use of machine studying, as a substitute saying “a number of parts go into the autos’ dedication of the place to park,” in response to Nihalani.
Koopman says that whereas Waymo could not have perception into how the vehicles are arriving at their parking selections, they completely perceive what it’s basing these choices on. “They don’t know why it made the choice, however they know what information they’re feeding it,” Koopman stated. The place it’s authorized to park is definitely on this information, however one Reddit consumer suspects that Waymos have “designated secure spots” — a suspicion that Koopman shares. Nevertheless, Waymo doesn’t verify the existence of such designations, and solely says that it prohibits parking in sure locations.
Tal, the Pico / Fairfax resident, feels barely uncomfortable in regards to the fixed presence of the Waymo with its always-on cameras; Redditors have expressed related sentiments. Delgin and Tucker have been principally amused, although typically aggravated by the automobile taking on a spot. As soon as, whereas about to go out on an errand, Delgin even made a rapid U-turn again into her avenue spot when she noticed a Waymo coming to dam it. This type of reasonable annoyance is the overwhelming sentiment on boards the place individuals increase the difficulty, too.
Some residents have taken their complaints on to Waymo, the corporate says. The factor is, Waymo shouldn’t be technically doing something incorrect, so long as parking doesn’t exceed three hours. Relating to parking laws governing Waymo parking, Los Angeles Division of Transportation spokesperson Colin Sweeney cites Los Angeles Municipal Code 80.69.2(b), which says that industrial passenger autos underneath 22 ft should comply with the identical parking laws that private autos do, and that they will’t park in the identical spot for over three hours.
Neither Tal nor Delgin is bound whether or not Waymo has overstayed this time restrict. However researcher Hyland says that, in response to the combination / hypothetical information, very not often did any rideshare automobile park for greater than two hours.
Waymo can, and has, instructed its autos to keep away from sure spots. Waymo confirmed that it’s technically potential to mark a spot as a no-parking zone for Waymo autos, which it has achieved in response to neighbor complaints. The police departments of Los Angeles and Phoenix weren’t capable of say whether or not they had gotten any basic “loitering” complaints, as most of these info requests require that inquiries be pinpointed to particular places.
“We’re dedicated to being good neighbors within the communities we function in,” Nihalani stated. “We’ve got acquired a number of items of suggestions from neighbors, and have made changes accordingly.”
Being a “good neighbor” is all effectively and good, however not offering readability into the particular parking conduct may point out bigger issues if it is usually utilizing machine studying for different capabilities.
“[Parking] shouldn’t be excessive stakes,” Koopman stated. “However firms like to make use of, ‘Effectively, the pc simply did what it did, we don’t know,’ as an excuse for shirking accountability for choices that could be considerably dangerous.”
Recently, the Delgin / Tucker household’s Waymo has been round much less. Waymo confirms that, whereas utilization fluctuates, it has seen a major uptick in current months. So possibilities to cease and take a breather for the robotaxis could be fewer and farther between as the provision of Waymo’s 500-strong Los Angeles fleet begins to fulfill Angelenos’ demand. Lisa Delgin simply hopes, sooner or later, a Waymo might be round when she wants it.
