Dashcam car accidents on You Tube?
I have dash cams in all my vehicles.
It paid off when a kid on a bike ran a stop light and rode out in front of my wife. The camera showed the red light, him riding up the sidewalk and him and two other kids turning directly in front of her. The cop (town cop) was amazed when he saw it. He told me later that he was headed over to the other kid's houses to have a "chat" with the parents.
Fortunately, the kid wasn't hurt except for a scrapped elbow. His mom actually sent us a bill for the bike... Which I laughed at... If that had been me when I was a kid, I would have been walking that summer. Same for my kids. No new bike and maybe, maybe, if I was really good, a used bike the following year. Never heard again from her or I would have given her a lecture on "parenting".
