Lane specific driving directions? How many Wifi access points and Bluetooth beacons is Google expecting to find on the highway while moving at 70mph?

I would presume they're hoping to find the devices of other nearby users?

Refusing service when the user does not consent to non-essential data sharing is illegal in the EU, and it also breaches Google Play's developer agreement. WiFi scanning is not essential to navigate with an app, and the least they could do to follow the law is to gracefully degrade the service if the user does not consent to share data about nearby devices, such as disabling traffic predictions. Of course Google's la…

Information about nearby devices is not essential for navigation, otherwise the permission wouldn't have been optional until now. It can improve the service in some situations, so the right way would be to explain the tradeoff and let the user control how much data is being shared.

I sense op feels entitled to use free Google services and dictate how their product should work.

There are many arguments why using GPS alone is both battery intensive and also more fragile as it won't work near tall buildings, indoors and takes time to localize.

But at the end of the day if you don't trust some corporation you can stop using their free services when there are alternatives around.

There's Apple maps, Bing maps, Here maps, etc.

How about in town, going 20mph?

Most of the android tracing that I've seen logged on location history is wifi multilateration based. Since wifi is on most of the time, it's the quickest way of finding your location (since you're most likely on the road), and you can turn off GPS saving about 25mW or more of power.

Why do you think the Goog's apps are bound to the same terms as other developers? That agreement allows devs use Goog's services.

But those would be in random cars around you, which are constantly moving. How could those help retrieving your own location on a map?

What is the value of sniffing the local ssids? As far as I know it is just to get a better and faster lock on location (sometimes GPS signals are weak) and therefore give better navigation. Does anyone know of some other purpose?

Back when I was working on location for Google Maps navigation, we explicitly disabled the wifi-based location service, because it was less accurate, and occasionally started giving locations from several seconds ago.

So to me it's kind of a baffling decision.

Can't believe I'm on this side of the debate, but at what point are we asking too much for free? Google provide Maps for free to an incredible accuracy and value. Unlike Apple, the user is welcome to use any other app, and yet chooses to use Google Maps. You could maybe argue that Google Maps is part of a package you bought the phone for, but realistically I think the solution is Google are just open about the use of…

At the point where Google's failures to release working, marketable, and financially successful projects are causing them to leech off freeware. Remember openstreetmaps is also free. I fully support freeware being paywalled as that would decimate FAMANG's userbase.

If I ask Google Maps to provide my cycling directions, I get multiple options depending on destination. If I ask Apple Maps, I get an apology that directions are not available in my area. I don't think Googs is using openstreetmaps data

Not really. That accuracy is not done with RSSI measurements from far away SSIDs.

Of course, though giving yourself an advantage over competitors in a market you control is also illegal, so they should at least try to keep up the appearances.
