Scratch, how did this turn out?
Other driver apparently didn't file a claim against us. My insurance company decided it was one driver's word against the other, so both drivers will pay their own repairs. My 19 year old son was in the car with my wife, but he wasn't allowed to be a witness, so there were no official eyewitnesses.
No tickets wrote and no insurance claims. Damage was very minor to my wife's 2008 Ford Escape, estimate was $384 to fix a one inch crack and touch up some paint chipping on her rear bumper cover where the Mercedes front tag hit it. I can fix this myself. My other son ran his car into a ditch a few months ago and cost $5400 to fix, so I'm not really upset over this minor accident with my wife. Its really not worth hauling someone into court over this.
I just found it unbelievable that somebody can be sitting still and get hit in the rear, and a police officer just takes the other drivers word about it. I always thought a hit in the rear accident would be obvious as to who was at fault. I don't have a lot of faith in my local police department after this.
