Google Maps Location History is showing an incorrect location I have a major problem that I hope someone can help with. On my Google Maps feature under my Location History it shows a location that I was never at at any point, but when my wife happened to see that location she doesn't believe me that the GPS could be wrong and pinpoint that location if I was never there.

I was first wondering myself how could that could be possible if I was never there or my phone was never at that location that was 35 miles away from me and second is there any way I could prove the GPS being wrong? Can I contact Google Maps and can they give an official printout of that certain day and every location I was? I really need to prove my honesty to her and hope there is a way.
From Google's Location Source and Accuracy page:


  Data sources
  
  The following location data sources may be used to derive location:
  
  
  GPS: GPS accuracy can be up to several meters depending on your GPS signal and connection. Your phone must support GPS, have it enabled,
  and allow Google Maps access to it.
  WiFi: WiFi (wireless network) accuracy should be similar to the access range of a typical WiFi router, or about 200m or better. Your
  phone must support WiFi and have it enabled.
  Cell ID: Cell ID (cell tower) accuracy depends on cell tower density and available data in Google's cell ID (cell tower) location database.
  Accuracy may be approximated at distances up to several thousand
  meters. Note: Some devices do not support cell ID location.
  
  
  ...
  
  Note: When Latitude is running in the background, it will default to
  cell ID (cell tower) location on most phones to preserve your battery
  life.


So if you didn't have Google Maps open for any reason at the time of the erroneous location, it will have defaulted to it's least accurate location finding service, that depending on the density of cell towers in that area (generally more dense in urban areas, less dense out in the countryside) could be out by several kilometers.

If you visit the Location History page in your Google account on a PC, at https://maps.google.com/locationhistory/b/0 then it should show a similar map and listing of places as you see on your phone, but you can also click each recorded location to see how (in)accurate it was. When you click the blue dot for a location, Google draws a blue circle around it that shows approximately the (in)accuracy of that location fix. 



The picture above shows an inaccurate fix that covers 3 villages, and a number of roads (I was actually on a train at the far southern edge of that blue circle).

As long the problem location fix has a large blue circle around it, and you can account for being somewhere in that blue circle then you should be ok.
