Finding your location within 100 miles
Is generally not a concern. I'm sure we can all come up with examples where it is an issue, but in the grand scale of privacy issues this one is so far down the list I don't think it is worth worrying about. Even then you can probably only get within 100 miles in fairly densely populated areas, with less precision the less dense the area you live in. So it would be lucky to pinpoint what state you live in, or what country in the EU.
