Is it law that everyone has to have a camera in Russia?
I am just amazed how many videos there are.
Does anyone in the States have a dash cam besides the police? Why do all of these people record their driving - for insurance purposes?

Cost and availability. This isn't anything new in Russia, the bad driving that is, but because of insurance(costs and frequency of claims) and legal reason they've become madly popular.
Same with motorcylists that commute here in SoCal and with their insurance within the past 5-years, the technology and availability/cost is right, and with the way the roads are they very very quickly pay for tripple their weight in gold to insurance companies and motocyclists to have a helmet mounted/built-in digital camera (from bentleys not signaling or looking before a merge to cops giving bad tickets - I've seen some videos, the best are the ones that show the other driver's reaction after they're informed it's all on camera).
