True, there's friction there. The problem I have is more with the lack of accountability, even to see who authorized it after the fact. All it takes is one stalker type with access to these and they can follow their ex around all day, every day.

I think someone else hit the nail on the head elsewhere when they said that they wouldn't be comfortable with their neighbors doing this. I think that's relevant, because it exposes that normal people do see a privacy interest in having someone follow you around, whatever the law may currently say about the existence or non-existence thereof. Maybe it's not a reasonable expectation, but that doesn't seem right to me, even if our privacy is steadily decreasing.
