In Russia it's hard to say, but in the U.S. I recommend that if you operate a commercial vehicle that you install one. If you operate a business and have people driving for you, you can review the footage and get rid of the problem employees before they cost you a million in insurance losses. After installing a system for a transportation company reviews of the tapes showed that 75% of the drivers were talking on their cell phones. They had a company meeting and showed a compilation video of all the phone video, even though it was now against federal law to do so. After that point drivers stopped using the phone while driving.

As the driver the camera is a mixed blessing, if you cause the accident, you've created your own evidence against yourself. If you the owner, it makes it harder for the employee to lie about what occurred if they were in the wrong.

Doesn't this mean the camera was pointed toward the driver and not the road?

Two cameras in the same unit. It's pointed at both.

Do people who have seat belts pretensioners need them so much or they are just overreacting? If you get into an accident it's better to have them than not and it's same with a dash cam.

Also, the same type of people who posts pictures of their food on Instagram loves to post videos how they passed a Ferrari from a green light or dodged Putin's motorcade etc.

Yes, this is really what I'm wondering.
