Stalkers will like this ...but then so wont the FBI/US Government??? I do hope Google are able to prevent handing over this very sensitive and personal information.
They likely will, occasionally, and if they do it without a proper subpoena (which certainly does happen) then I hope they get busted (and they might not).
But for anyone who worries about that to the point of wishing the app didn’t exist, why not just worry that there’s a government GPS chip inside all kinds of devices you never suspected? Your flashlight, your car, your belt buckle, your shoe... or your iPhone GPS itself, turning on six times a day to send your location due to Apple iOS team being infiltrated by government spies.
Privacy and corruption concerns in the US can be absolutely valid—but a visible app that you choose to install and then choose how it tracks you, with a hacker community watching it for unauthorized transmissions, is not any more troubling than the simple fact of carrying anything big enough to hold a battery and antenna

(Now that’s good paranoia!)
I’d like this for finding friends who are hiking when we start at different times or from different trailheads. Or at big festivals/trade shows. Or in shopping districts, malls and amusement parks. Certain specific uses. (Which the iPhone can already do up to a point: you can SMS your location from one iPhone to another.)
the criminal energy and inventive spirit of a criminal mind or a government will find a way to track you regardless what you have set in the phones settings.
Or whether you even own a phone at all. (Since we’re talking about whether you COULD be watched, not whether people ARE watching you right now.)
I predict that Android-like gMaps navigation in iOS won't happen anytime soon, if ever. Google wants to maintain some differentiation between "native" Google-experience Android devices, and competing mobile platforms (iOS, WebOS).
Built-in navigation in Android devices is one of the key differentiators (as long as few other like truly integrated Google Voice), and Google will want to keep it that way.
Possibly—but I’m not jealous of Google navigation anyway:
* It only works where you have a good Internet signal. I’ve seen that bite my Android-using friends, and in rural areas or on longer trips it’s inevitable. Or, if the signal is there but weak, it’s just really slow (the image detail anyway).
* Excellent iPhone navigation software is cheap: I got Navigon MyRegion for $25, and even when not on sale it’s a good buy. There are other choices too. And they work, quickly, with no cell coverage at all! (But they do take up space.)
You can buy Navigon etc. for Android too—at least in some countries—so this is not an iPhone advantage. But it makes the Android built-in app more of nice little thing and not a killer feature.
By the way, iOS GPS multitasking is great. I can run Navigon in the background, with full voice guidance and re-routing as needed, and run ANOTHER GPS app (no jailbreak needed) in the foreground. I use either Google Earth (free) or the regular Maps app in the foreground. I then get the nifty satellite photography (and I see my position but not my route) but I can fall back on Navigon if I want to see my route details or if coverage lapses. I assume Android can do the same, with equal battery efficiency, but then I’m always assuming Android does what my iPhone does and being surprised to be wrong
