A friend's car is parked on her drive - there is a t-junction opposite her house off the road on which she lives Car A comes out of the road opposite her drive - skids into car B which is traveling down her road. Car B is knocked into (drives into) her car (on the drive).
I assume that she does not have to go via her own car insurance firm and can deal directly with B's insurance.
What would you do? - advantages - disadvantages?
