Google maps also includes towns in rural areas that don't exist. There are 4 listed within 20 miles of my house that haven't existed for well over 100 years. They're not incorporated anymore, and they don't exist on any other maps, just Google. It's weird.

Could be copyright traps to detect unauthorized copying of the map: https://en.wikipedia.org/wiki/Phantom_settlement

Good one. These are the real easter eggs

Your comments reminds me of “ Falsehoods programmers believe about addresses” https://gist.github.com/almereyda/85fa289bfc668777fe3619298b...

I skimmed and I think that's missing That a building|property will have only one address . Sometimes (eg: rural Australia) property addresses are updated from an older numbered lot based system (that goes astray when properties are subdivided and infill houses appear) to a system that numbers houses by driveway distance from last major intersection. For five or ten years a house can be recieving mail or be on the rec…

It also happens in places where a house/building spans two streets, and gets an address on both. Same reason some buildings get multiple numbers on the same street (happens a lot if they want to keep the option to later split entrances and give them numbers for instance)

I wonder if trying to support strange international address styles (like cities where the numbers on the street are in order of building permit issued, not ordinal from a center point) and/or trying to scan imagery for addresses is confusing it. The fact it gets the street wrong indicates a tokenization issue somewhere. Any evidence it happens to non-numeric streets like Main Street or Martin Luther Blvd, or is it on…

>like cities where the numbers on the street are in order of building permit issued Holy shit what an absolutely needless nightmare of a system. How do you expect people to find anything like that?

Hey, at least they have numbers!

In some areas the streets have no names, nor do the buildings have numbers.

If there’s three streets and twelve houses, why do you need any of those?

In the logistics industry the commonly held wisdom is that there really isn't any accepted system for "how street addresses work". Different countries have completely different systems, and even within a country there are often many different conventions. The thing that really matters in delivery is whether the address on the consignment has enough information for an operator to complete the next leg. By the time an…

> it’s probably not feasible for a global product like Google Maps to understand and encode every regional system

Does it have to encode them all? Why not start out with one then at least Google Maps is a little better for some.

Besides that, how many systems could there be? There are only something like 10,000 cities on the planet. That sounds like the kind of task Google is built to handle.

"Is the parcel in the geographical bounds of the city name entered?" The "city name" on an address isn't really a "city". SFO's address is "San Francisco, CA", but is not within SF city limits. Queens NY addresses have "cities" that are just neighborhoods. Applying any kind of logic to addresses will just be a minefield.

The Pentagon's address even has the wrong state. The address is Washington, DC, but it's in Arlington, VA.

I've noticed some really strange lapses in transit directions as well, though there it might be more directly blamed on the source. Confusingly, for example, Google thinks it sometimes takes like 20 minutes for the metra electric to go from Van Buren to millennium stations (a distance of perhaps half a mile). What I believe is happening is it's using the departure time of the train from millennium station (it will la…

I do not know whether Maps shares data with the Waymo service, but their pathing has driven me bonkers for awhile now.

Waymo is convinced that it is impossible for a pedestrian to walk from where I live to the east side of my lot (I live in multifamily, 300 units).

Waymo seems to have pedestrian pathing in mind, and will block the app from a walk that is too far away.

The landlady provides custom made pickup areas in the east lot, but Waymo keeps insisting on pickup and dropoff on the west side.

Adding insult to injury, the “set on map” feature of dragging the pin has been broken as well.

So I have to put up with it. I mean, they’re still in “testing phase” but I’ve given them such clear feedback, they are surely aware by now.

For a practical example here, check out Mumbai, India in Google Maps and look at addresses of various businesses there, most of which amount to "Building Soandso on Road X near Landmark Suchandsuch in neighborhood Y" (ans often written in a non-standardized way, on top of that). To compensate, delivery apps there have you visually put a pin on a map as a standard part of checkout flows.

Not sure it's related, but recently I tried to ask Google maps to find a way to a train station, and it confidently set the destination to the exit of a nearby highway. Yes, I double checked that I was using driving navigation, and it expected me to stop the car in the middle of the traffic. And I have no idea what to do about this. P.S. I never had good experience with reporting errors. Sometimes they are rejected d…

I've had this happen to me too. I would drive there, and while still on the highway Google says I've arrived. I don't stop the car in the middle of the traffic for obvious common sense reasons, I just switch to reading the signs nearby to get to the train station or the airport. When I grew up there wasn't turn-by-turn navigation at all, so I still treat it as merely an aid and not gospel.

Google Maps has declined remarkably two or three years. It’s now an ML-brained mess. Like the rest of Google. Apple Maps is actually better now! That’s incredible.

I don't recall last time Google Maps made a mistake for me. I'm sure it has messy data. I don't envy developers that have to work with geography or timezones. And Google Map devs have to work with both. Ouch.

Google Maps often has problems adding stops between where I am and where I’m going. I experience this the most when I’m driving cross country on an interstate and I search for restaurants. It often thinks I should turn around and drive back 5 miles to go to some restaurant that I’m guessing is paying Google to send it traffic.

What I really I want are options between where I am to where I might be in 30 minutes.
