I saw this (Peabody's) video a month or two ago. It was apparently taken in Russia, where almost everybody has a dash-cam. Not sure what the reasoning is behind all the dash-cams, entertainment or proof of liability? If you look at the road signs (before the crashing and explosions start), they appear to be in cyrillic.
However, having been hit in the driver's door (Mazda 323) by a Kenworth turning right from the left lane while signalling for a left turn...and in an illegal turn...I don't trust "professional" truck drivers very much, and do my best to stay the heck away from them. They're not as good as they used to be, for sure.
