ya, i agree tat run away is the best if you ownself is okie, who
cares about his car anyway. 
i happen to haf the same experience as you also.
was on 1st lane when a car just turn into the side lane at my side,
i horn and siam him so i did not head on on him. my brake pad was
slightly lifted, but usable, crashcbar dented, but i saw his car
haf 1 big chunk of paint came off, i faster run, save the arguing,
cause im always right.
