Virage Is The Sexiest Car On The Planet

[Editors note: This post originally ran on Dec. 12, 2012. A meteroid that exploded over Russia Friday morning, flooding the Internet with tons of videos within hours of the event, suddenly make it relevant again.]

Videos of car accidents filmed from dashboard cameras have become such a popular genre on YouTube, it seems every driver must be filming his every move.

Why is that?

In a post on Animal, Russian ex-pat and journalist Marina Galperina offers a few reasons, which boil down to dangerous driving conditions and the unreliability of Russian traffic police.

Driving in Russia is hazardous: Last year, 200,000 traffic accidents killed 28,000 people. (More than 32,000 died in car accidents in the United States in 2011, a much lower figure per capita.)

Addressing those high levels in 2009, President Dmitry Medvedev blamed the "undisciplined, criminally careless behavior of our drivers," along with poor road conditions.

Drivers certainly play a role, but Medvedev did not mention Russia's traffic police, which, Galperina writes, "is known throughout their land for brutality, corruption, extortion and making an income on bribes."

That is not hyperbole. Russia ranks 133rd among the world's nations in corruption (where number one is the least corrupt), according to Transparency International. Much of that corruption is on the part of the traffic police, an institution that, along with kindergartens and higher education, was ranked by Russians as the country's most corrupt. In a recent poll, 32 percent of Russians surveyed called traffic police the most corrupt institution.

So going to the police with a legitimate complaint is far from sure to produce a good result.

In addition to authorities they deem untrustworthy, Russian drivers must contend with the possibility of being attacked by another driver. The below video compiles fights between drivers that feature crowbars, slapping, punching, and worse.

Then there are pedestrians who get themselves hit by cars on purpose, for a payoff. A video compilation (below) of failed scams offers a few examples.

Overall, in a country where traffic conditions are horrible, insurance scams and roadside fights are always a possibility, and the police are widely viewed as corrupt, video evidence of one's innocence can be a very valuable thing.

Here the fighting compilation:

And the pedestrian scams:
