SWAG assessment?
You have to have a signal over a certain threshold to carry a call. Signals below that threshold might still be good for text messages, or high latency data use. These same low-quality connections also tend to make your phone louder. When you don't have a good signal, your phone's standby battery life shoots way down because your phone is turning transmit power to eleven to try to pick up a usable signal.
In a situation like this, where your phone is hopping between any towers it can find, transmitting at high power, I would tend to think you'd be easier to track than in a situation where you have a very high quality connection, and your phone doesn't have much incentive to try any other towers.

good info … my phone (if left on and in certain places in the house) will tend to drain much quicker than other times …. which is why it's turned off a lot of the time
and sometimes when it's been left on, and I for some reason or another move it to another part of the house … I'll suddenly have a couple of text messages (sometimes a couple of days old) to pop up … so I'd guess not even enough signal getting through for even that

My grandfather told me when I was little that on the Ohio Turnpike, they time stamp the ticket, and they'd give you a speeding ticket if you went through too fast.
About halfway between then and now, I had a commute that took me across one exit of the Turnpike. (I-480 to Midway Mall, for you Clevelanders) $.50 saved me a bunch of time as the Turnpike was diagonal vs. cutting through a lot of city traffic. And there typically was next to no traffic, and never any state troopers, so I used to just park my car at 110-115 the whole way.
Never got a ticket. Maybe the couple of minutes waiting in line at the exit booth took up the slack, maybe they just didn't care.
When I think about the things I used to get away with, that I wouldn't dream of trying now...!

I've been running the PA Turnpike non-stop from Breezewood to Irwin and back 10-12 times a year since 1966 usually at 10 over. Never had anyone say anything or gotten any tickets. Always been driving some pickup, van or generic family sedan so maybe I don't attract attention.
That same story occurred when the NYS thruway (I-90) opened.
No one ever got a ticket.
The time is used to monitor traffic flow.

the GPS data on a dumb phone is not available most of the time, it's only intended for E911 use, has to be specifically turned on by the base station, and there's limited capacity to run it. Smartphones have their own GPS receivers, but they don't upload that information to the cell carrier. They *do* upload it to Google if you have that enabled, so in theory someone could use that to try to write a speeding ticket. I'm not a lawyer, but I suspect there'd be all kinds of problems with using that as evidence, however.

E911 is not the feature that makes your phone trackable as long as it's connected - cell tower triangulation is. If you have a phone signal your phone is connected to one or more towers whose locations are known. No GPS receiver necessary.

I wish they'd link the insurance and registration in my state. The number of uninsured keeps my premiums amongst the highest in the country.
NV also has the insurers report directly to the DMV. Not sure how we rank across the nation for insurance rates, but I'm always impressed that uninsured/underinsured motorist cover tends to be a substantial part of the premium on the cars and usually over half the premium on bikes.
As it was explained to me, the 5th amendment makes it illegal for toll roads to use your own transit times as justification for speeding. I think it has something to do with the "nor shall be compelled in any criminal case to be a witness against himself" bit.

Privacy though? I know none of us EVER read through that whole "you want a cell phone?" contract. And nobody ever reads through the "terms of use agreement" when you update your phone or computer.
This allows these organizations to follow you by any means. Example- playing pandora on my phone in my car, I drive past Home Depot, and BAM! A Home Depot commercial comes on.
Wife and I are in bed talking at night and the tv in the background plays a commercial about Viagra, I had my iPad on and using safari I visit a page, no sooner does the webpage load and what ad do I see for the side bar ad? Yep, Viagra.
I am an appliance technician and everytime I fire up my iPad at a customers house the ads on whatever website I was previously viewing end up being for appliances like washers and dryers.
You can't say they aren't listening. We gave them the permission to, now they do. soon tv ads and the like will be focused just for you.
If you don't want to be a fish, leave the stream.
That's why I live in a po-dunk town. My back roads are still deserted, my internet comes and goes, and my cars (At least the ones I care about) are carbureted.
