Had an accident several years ago, I was 100% sure that the other car ran the red light. Of course the other driver lied and nobody was determined at fault since there is no evidence nor witness (midnight). Later in police report I saw the other driver is DRIVING WHEN SUSPENDED, NO WONDER WHY. So I bought a dash cam. I recently bought a new one that acts like a rear mirror (it also has a rear camera that I didn't use). I think it's pretty cool so I don't need to stick it to my window and fall off due to day/night temperature change. No accident ever since but it makes me feel safe :)
