she could request a video link to a court more local to her meaning she loses less in getting to court?
there should be atleast one local copper that knows that island like the back of his hand so he can provide evidence that its only ever been a 2 lane island not a 3 lane.
also tell her to learn to notice stuff like that better. same happened to me on the way to work last night crash was avoided because i noticed them, and then gave them the aggressive driver routine from behind with lights and horn
