I’m not opposed to them but I don’t have one. I can see where it would be useful if you’re in an accident or someone does something like cut you off, it would be helpful to have as evidence. Another example of a good use would be if something occurs outside of your vehicle, not traffic or driving related and you’d like a record of it.
I’m in a group on Facebook that is specifically for a local commuter highway where people post dash cam footage all the time. After a snow storm where big sheets of ice come off the vehicles and fly all over (sometimes cracking windshields) is something that is often posted.
Recently there was an incident where there was stopped traffic and a truck driver and a driver of a car got into some kind of altercation, and the car driver had a machete and was threatening the truck driver with it. The truck driver kicked the guy’s a** and the machete guy got arrested. There was dash cam footage of the fight and it was fascinating to watch.
Sometimes things happen where you’re accused of something by a police officer and maybe you are not guilty. Maybe the police officer was located in a spot where he couldn’t quite see things the way they actually occurred. That would be another example of where it would be helpful to have a dash cam.
Costco has a dash cam for about $100 right now.
