Re: Northridge isn’t rural
In some ways it works the other way 'round -- if you're in an urban area and you hit a 5G microcel it's easy to know your location to within a few blocks. If you're in a rural area you might be on a tower that covers ten miles or more.
There was a case in rural California where the cops tried to use a cell phone tower ping as evidence that someone was at the location of a crime...problem was only one tower covered the whole town, which the suspect lived in, so the chances of his phone hitting that tower were 100% whether he was involved or not.
