What the heck became of common sense?
I was faced with just that situation a month ago, only from the wrong end. I came over a hill at the legal 60mph on a paved road and was faced with a pickup pulling a disc that covered a good 3/4 of the road. I stood on the brakes, he headed for the ditch, and I somehow got past without hitting the disc. I'm not sure if he got out of the ditch and back on the road, 'cause I was over another hill.
If you got home without killing somebody, you got off easy.
