My experience speaks otherwise. They first will ask why why why (you know ) then request a police report. The collision center will ask why why why again. Then you will wait .... weeks, you called back and got to the case handler,....then they said the other party info is incorrect (god knows how)
In the end you will waste so much time. They even refused to pay at one point accusing its a single vehicle accident. Until threatened to take it to insurance liaison officers.
Too be honest, **** all this. I will never go thro private deal and BS again. Its their fault then let insurance deal with them. DONT LEAVE untill you got a police report, contact insurance right after.
