So I was in a 4 car nose to tail accident this morning. I was the third car. The first car admitted they braked by accident. The last car (the one behind me) was trying to convince every one to sort it between ourselves and not involve insurance. DH thinks I should go through insurance, I dont know as the damage I caused to the 2nd car was very minimal but the damage 4th car caused to me was quite significant. WWYD?
