Here's another one;
Driver in Hope killed by falling rock
They did catch the offending driver, but if memory serves me correctly he was found not guilty of any crimes.
I touched base on this a few days ago, but the discussion got rather heated so I believe that I deleted my posts. Some people think that it's funny to mess with their fellow motorists. I've had people straddle the lane so that I couldn't get past; or speed up 30 mph when they get to a truck lane, only to slow down when they come to the end of the passing lane. Worst case was when I was on my way home after a long day, the guy would slow w-a-y down until I passed, then speed up and go by me, only to slow down again. Twice I pulled over and read a book for a few minutes because I was getting POed; only to have him waiting for me 1/2 mile down the road.
