These people are not getting caught. New Yorkers have very elaborate ways to avoid tolls and speed cameras. One popular trick is to have a lever which engages a shutter that covers their registration plate, which they engage only as they approach a speed camera or toll gantry. As soon as they are out of sight of the camera, they roll the shutter back up.
This modification, of course, is highly illegal but it's very difficult for the police to catch unless they stake out the camera and wait for someone to do this in front of them. Police do occasionally do that, but it's obviously not a great use of police resources to sit there and simply hope that someone is stupid enough to do this in the sight of a police car.

I think there is a line to be drawn between what is theoretically better and what is meaningfully useful.
It is realistically not useful information for an attacker to know what country you are from by observing your UTC offset. It's simply much easier to guess this information by observing your other behaviours. For example, the text and time of your post is already leading me to guess UTC+5:30 as the time zone in question. But again, knowing what country you're from is not really useful information most of the time, as even if my guess is correct, that narrows it down to a whopping one-eighth of the human population.
