I was in an accident many years ago.
The other driver's insurance company phoned me to state that they felt it was my fault and payment wouldn't be coming.
I was confused and thought it was my insurance company I was talking with, and so I figured they needed "help" and offered to send them the video of the accident.
The agent was surprised I had a video, and then said it wouldn't be needed. They paid up right away.
Funny part was I was thinking about video from my cell phone after the accident, but their reaction convinced me to go buy a dash cam for next time
