Remember kids, there's a pernicious reason why #Google redirects "http://maps.google.com" to "http://google.com/maps".
Because of this redirect, the location permission that you grant to Google Maps also automatically becomes available to Google Search - making your search queries more valuable to advertisers.
@nilesh as an ex-Google privacy person it makes us very happy that people who aren't under NDAs talk about this (you're the second we've seen to mention it, the first was several years ago. might have also been you actually, can't remember)
