I think you can say that all insurance have at least partial network effect built in. Quality of underwriting comes from a diverse and large risk portfolio, which leads to profits and pricing accuracy.
Locksmith use to do the same kinds of scam on 411 services and yellow pages listings. The fees to have multiple business phone lines with the phone company was the real curation.
You can also have a convoy of 1 manned truck with n driverless truck that play follow the leader. You end up with a train model on the road infrastructure.
Once I heard Marissa Mayer recount that she asked Sergey Brin where he got the idea of doing such a minimalist design for Google. Sergey's answer was: I don't do HTML.
The formula by Sivers he refers too seems to be the best approximation to value idea. I still like to put emphasis on execution instead of idea, since almost everybody I talk with that value idea is in fact doing some analysis paralysis and will start working when they get that "great idea".

I saw her current net worth being evaluated at $300,000,000. I doubt this moves has anything to do with money, but she would not want to be seen as a cheap hire either.
The article cited never asked "Is 12,000 ...". They say "Look cameras are not that bad since most are on premise and are privately owned and operated." I find that this comparison is dishonest and is not relevant.
edit: changed "you cite" to "cited", The response is not to the OP.
The fact that the majority of camera is privately owned is not relevant. The question remains: "Is 500 cameras too many, too little or just about right, for a county of 1 million?". I have no idea, but I don't see why the ratio public/private is important.
I used it while abroad. Since the GPS works, you can see where you are on the map, which is a big plus over only a paper map. Obviously getting data access would be even better, but it's a nice free alternative.
