Yesterday I was driving on a busy highway during a downpour and a guy swerves into my lane so I hit my breaks to avoid hitting him.  I start hydroplaning, my car spins out of control, and I wind up hitting the concrete divider.  My shoulder hit the car door and dislocated but I'm by and large okay.  My car isn't even that badly damaged; looks like repairs will be around $400 or so.  
However, the a$$hole who caused this just drove away and probably doesn't even know he did anything wrong or that I even exist.
