I would also like to note that the dashcam saved us from a potentially long argument with the insurance providers as the police made absolutely no determination on the scene about what happened or who was at fault. Once I grabbed the dashcam from the about to be towed X5, retrieved the footage in my own vehicle, showed them what happened, they verbally stated that they would issue a citation to the other driver in the hospital.
No argument with the insurance either, USAA accepted responsibility without any issues.
