Just do what my brother did when a lady turned left infront of him and she was clearly at fault. The insurance people had the same line, "well we still have to wait for the police report to see who was at fault". My brothers reply "She already admitted to a cop she was at fault and ya know, i think my neck feels like a lawyer coming on", next day an adjuster called and came out the same day. Six days after the accident he did get a sore neck and back so he collected on the medical too. It's a waiting game so document everything and be patient.
