Actually, yes they do. People think it's the police, but it's not. It's the insurance company, specifically the adjuster.
As many of you know, this is what I do for a living. I can explain it simple. Money. Money. Oh, did I mention money?
They're probably not actually injured. But here's exactly how this works....
Plaintiff lawyers have people who's job is to do nothing but scour police reports, scanners, etc...to find clients. They go recruit them and whisper all kinds of sweet things in their ear. The attorney will tell them what part of their body is hurt and what "doctor" (chiro) to go to. The chiro, which is just as shady as the lawyer, will tell them exactly what treatment to get and how long to get it, no matter what. They run up as many bills as they can, to make the claim look as big as they can. The "treatment" is usually a bunch of unnecessary x-rays, useless scans, then massage, ice packs, hot packs, e-stim (again, nearly useless). The attorney then sends a "demand" to the insurance company seeking a very large sum of money. Negotiations happen, the claim is settled. The attorney keeps 33-40% of it, which is basically most of the money the client would have pocketed on their own after paying the medical bills back (the attorney gets a kick back from the chiro too). If it doesn't settle, they will file suit. And it's not the insurance company they sue, it's you...the driver. The insurance company then has to spend more money providing a defense.
Before anyone gets all up in arms, yes, there are legitimate injuries that happen in auto accidents. No doubt. Those ones are REALLY a shame when an attorney gets involved, because they really take advantage of the injured person, in order to line their pockets. Often, they can interfere with the client getting the treatment they really need. Anyway, those cases are more of an exception. The majority are from the slimy attorney office that advertises on TV, with people who really aren't hurt, but want a payday.
OP, if you have any specific questions, don't hesitate to ask. If it is a TV attorney they hired, don't worry, it will definitely settle. Those law firms wouldn't know the inside of a courtroom if they stumbled into it...they don't litigate anything...they're just churn and burn operations.
