A friend is, we think, the target of an fraudulent insurance claim. Someone has accused her of causing an accident in a supermarket carpark and driving off. As luck would have it she went to get petrol from the supermarket petrol station (hardly the act of someone driving off from the scene of an accident) and her receipt shows the exact time the claimant says she was hitting his car. However she now has the hassle of the police coming to inspect her car (which of course has no damage whatsoever on it) and having to prove her innocence. We are hoping the CCTV in the car park and the petrol station will clear her, but my daughter suggested that a dashcam would have proved her innocence immediately. Does anyone have experience of different makes of dashcam? Also is it possible to have a lengthy time loop, because if filming is overwritten too quickly this incident would have been wiped before the insurance company got in touch with her.
