It definitely does seem potentially kinda creepy or weird initially, but if you do truly trust each other, it's actually really useful. e.g. You can passively see where someone is before nagging them to ask if they're going to get here soon, etc.
You can also configure the phone to send out its location just before its battery dies.
The disconnect here for me is that your hypothetical is hardly a new phenomena unique to our time. What would you have done in the 50s? 80s? 90s?
Let's put things in perspective here. The very fact that you can have real time updates on the metrics off the /device/ that is expected to be carried with your son means you have a direct channel of communication to your son's device. Worried? Give him a call. Problem solved.
Why? I always see such massive push back to technology in what would theoretically be a tech-adopting crowd.
Why would i, as a band playing Son, want to have to stop practicing or playing a set to call my family back in a timely manner? Couldn't some technology, perhaps a device in my pocket, allow my parents to know where i am, handle the burden?
Why is my mother knowing where i am such an invasion of privacy? Mind you, i'm 30 now, but i don't care if my wife knows where i am 24/7. Hell, i want her to. I'd also like to know where she is. We've got nothing to hide from eachother, so why should the 1950s method of calling eachother periodically to ping our locations be used? Why is 1950s your metric for success here?
I want technology to make my life less of a hassle. By all means, make it secure, i'm not arguing anything different. But i'd like to move beyond 1950 please.
"Giving him a call" is all fine, except if they are mid set or are tearing down while another band plays - stages can be loud places, and not the best things for talking on a phone, or even texting when they are busy moving gear. A quick check to see "Oh, he is still at the venue" or "He appears to be at the band's storage lockup right now" is enough for me to know that it is pretty much ops normal.
If they are 18 and paying for their own service, then fine, that's another story.
But until then, I don't think it even matters. Seriously, I feel people without children just don't understand how parent's feel.
Honestly, I don't think it really matters if your citizens are OK with it or not. They are still citizens and you are responsible for them.
If they are politicians and have a say in the service, then fine, that's another story.
But until then, I don't think it even matters. Seriously, I feel people just don't understand how the government feels.
If you don't put children in situations to experiment and earn your trust, they will never learn.
And yes parents worry, that's normal. If you lose sleep over your kid being out having fun with friends, it's perfectly ok. It's feature of raising kids, not a bug.
I think I have a pretty good trust relationship with my kids, but there have been times where they have been half an hour late home from school or a gig etc. and the worry button gets hit. In all occurrences, it has been simple things like missing a bus, or staying back to get help with teachers etc., but those are the sorts of things that I'd like to be able to check on quickly before resorting to calling/texting.
The ability to notice something is amiss, then do a quick spot check to see "Oh, its OK, he is still on school grounds" or "He's on the number 10 bus homeward bound" is reassuring.
EDIT: I just realised that I forgot to answer your actual question re: Are my kids OK with it (the monitoring).
Neither of them have pushed back much on this. In fact, last year I developed a small iPhone app purely for the family to use to achieve the sort of tracking this Google system does. My sons were actually quite helpful in helping me design and test it out. End of the day I abandoned the app because I just didn't have enough time to maintain it, and there were other third party apps coming out that did the same thing.
As mentioned above, we have a pretty good trust relationship with our kids. Its not as if we track their every movement, and we are quite flexible with them spending a lot of time out with their friends and other sporting/social activities. It is just on those outlying times where we feel the situation is not completely 100% rosy that we like the ability to do a quick 'ping' check.
