This YouTube video posted by user ;B200 Mercedes shows why having a BlackVue dashcam is worth it. In his own words:

This driver tried to crash into me to claim my insurance, aka Insurance scam. Almost got away with it if I did crash into him. Instead, he is looking at a judge in a court trying to explain himself with this video footage. Get a dash cam, its worth every penny.

Short, but to the point. This driver was quick ;enough to avoid collision, but not everyone is this lucky. Thankfully, your BlackVue dashcam will be there to protect you and help you prove what exactly happened.
