I had an interesting conversation with a claims adjuster for a major insurance company yesterday, which affirmed why I have dash cams in my cars. Besides recording accidents and incidents it will also save you from common scams: 1. Someone suddenly braking at a green light to make you rear-end them. 2. Waving you on at an intersection and then suddenly accelerating into it to make you hit them on the side. 3. Stopped at a red light, the car ahead reversing into the front of your car. 4. Pedestrian jumping onto your windshield ‘Better Call Saul’ style. You may never need it but if you do it’ll more than pay for itself the first time. Police have them. So should you.
