They get within a block accurate almost without fail. My wife has to do it all the time, on the working end of 911.
Though in afterthought this, of course, will depend on your general area's tower infrastructure.
It's dependent on a whole lot of things. Tower infrastructure is a big one, the protocol your phone uses to talk to that tower matters too, as does the type of buildings in the area.
I find it more creepy how accurately Google can get your location from wifi data, even without cell or GPS enabled.
Yeah, since so many of the wifi hotspots broadcast their own location, Google can usually get you to at least within the building. The technical aspects of locating yourself based on different wifi hotspots is actually super cool. Also, not very accurate.
It's interesting that HB, you seem to think, this is a good idea?
First you denied that the storage could be had... until I showed you how easily it could...
Now you say, well, they can't retrieve it...
How hard do you think that is? Especially if they do it after the fact... meaning, they've captured you and now have your black box.
Well first of all, I'm all but certain it's not a thing that's actually happening. Hence my lack of concern. Were it happening, I don't know that I'd mind all that much, but I wouldn't call it a good idea, if only because it would be a terrible waste of government resources.
And yeah, I suspect the whole storage space thing I was wrong about. But still, if the government has already apprehended you for something, then yeah, they could get to it pretty easily I suppose. I guess if you really want to carry on illegal activities in your car, you'll just need to disable the device.
The intent probably isn't to actively and at the moment listen in on people, they could just put a bug in your car for that... it's to have a record should something go haywire... like you get in a car accident... or you plan to rob a bank... or you're on the phone telling someone how your wife cheated on you (establishing motive type stuff)...
It would extremely useful in case of a car crash. I'm actually super in favor of "record the last three minutes that happened in a vehicle", with a simple continuous overwrite, for exactly that purpose.
As for those other things, that sounds like them using the information in a court of law? In which it would already be subject to the same reasonable cause and Fruit of the Poisonous Tree rules.
