Guys Im wandering if you can give me some advice. On taking a car crash incident further against, either the council or a farmer.

Yesterday my girlfriend was on her way home on a road she has travelled everyday for years. There is several bad corners and she was taking the last one of them to proceed onto a straight at 20mph when the back end steped out on her peugeot 206, she corrected it but it went the other way then violently did a 180 degree turn sending her sideways into a ditch and small trees, completly writing off the car. (See pic) The reason the car went is a combination of two things, the corners are very badly designed and are off camber and there was a thin skim of mud that had been carried by traffic to that point from a field entrance several hundred yards away, it had been very lighty raining which made this skim of mud slidey.
She called the police and they werent intrested in coming out, they just said are you ok and is the car off the road - yeas, Well just call your insurance was thier answer
The reason I want to involve the council is I am absolutly fed up of people writing thier cars off on these corners, each time I pass there is usually new damage or a car lying in the one of the ditches, there is 4 bad corners in this area.
This is the final straw that the GF has sucome to this, what can I do about the council and farmer?



Not very visable in the picture but the doors are knackered, windows smashed and all ripped at the b pillars, the quarter is also ruined and the tailight,
Thank you
