I heard about this too - apparently Russian traffic cops are rather fond of bribes and such, so a lot of people have starting using dashcams for that reason, hence catching great footage of the meteorite.
I'm not against getting one myself these days... so many crooks trying to sue you for every tiny thing they can get away with

I'd also like to hand the footage over weekly to the police to assist them in fining people for driving around like idiots, on the phone, running red lights... we have a pretty poor standard around here sadly.
