Here in America, dashboard cameras seem to be limited to Police cars.  They have proven to be very effective in helping the officers do their jobs.

However, that is not the case in other countries, especially in Russia.  Most, if not all, cars in Russia have dashboard cameras.  I don't know if it's a requirement, but from some of the video footage we have seen lately, it's a good idea.  They seem to have some wacky drivers and accidents over there.

Watch this as a truck tries to avoid a car that has suddenly decided to stop in the middle of an expressway.
