Um....hmmm, depends would rather have 1000 people looking at your plate, or 100,000,000.
I travel pretty much the same route/places in my personal vehicles, and if I'm playing the odds right, I'm going to say you've got less of a chance (though not impossible) to find a seriously demented person in the group of a 1000 people, than in the group 100,000,000. Especially if the 1000 are you own community.
This is just my thoughts from my gated community, since people of other regions don't really go unnoticed here, everyone is native, or métis.
I'm just saying there was one instance when a guy was looking to buy a truck off me, and he must have asked more than a few people about me, I was getting cell phone photos of the guy from like 6 different people.
