'Why Do Waymos Keep Loitering in Front of My House?' (theverge.com)

(Monday September 01, 2025 @11:12AM (msmash) from the no-place-like-127.0.0.1 dept.)


Waymo robotaxis are repeatedly selecting identical parking spots in front of specific Los Angeles and Arizona homes between rides, puzzling residents who [1]document the same vehicles returning to precise locations daily . The company states its vehicles choose parking based on local regulations, existing vehicle distribution, and proximity to high-demand areas but cannot explain the algorithmic specificity.

Carnegie Mellon autonomous vehicle expert Phil Koopman attributes the behavior to machine learning systems optimizing for specific spots without variation. Waymo said it had received neighbor complaints and has designated certain locations as no-parking zones for its fleet. The vehicles comply with three-hour parking limits, according to Los Angeles Department of Transportation regulations, governing commercial passenger vehicles under 22 feet.

Waymo has it figured out (Score:2)

I've been in San Francisco recently. In my daughter's neighborhood the streets are too narrow to allow two-way passing, so one vehicle needs to pull over (cars packed on both sides, and driveways are very narrow). I was heading downhill and I see a Waymo coming up. The Waymo found a nook, pulled over to let me pass and I rolled by without a hitch.

I hope you gave it a 'thank you' wave.

Is this even discussion. In the very first paragraph of the summary.

>> And there you have it. No news report required. The most obvious answer is also the most likely. The car is parked in front of that particular location because it's very likely close to a central point to where the majority of it's rides will originate.

That would be interesting because water isn't wet. Water makes other things wet.

"systems optimizing for specific spots without variation"

Pretty obviously exactly this. equidistant from A, B, and C or something like that. All they need to do is add in a small random factor to whatever algorithm they are using.

Ah ... "three-hour parking limits" (Score:2)

These are meant for humans, who would give up taking a car there if they need to re-park it every 3h, while it does nothing for self-driving cars (if anything it creates even more congestion from the cars re-shuffling all the time and is pissing away some energy too).

Next step (if not done already) is to play musical chairs between Waymos intentionally.

Deliberate provocation of mystical experience, particularly by LSD and related
hallucinogens, in contrast to spontaneous visionary experiences, entails
dangers that must not be underestimated. Practitioners must take into
account the peculiar effects of these substances, namely their ability to
influence our consciousness, the innermost essence of our being. The history
of LSD to date amply demonstrates the catastrophic consequences that can
ensue when its profound effect is misjudged and the substance is mistaken
for a pleasure drug. Special internal and external advance preparations
are required; with them, an LSD experiment can become a meaningful
experience.
-- Dr. Albert Hoffman, the discoverer of LSD
