As usual the story says nothing about the cyclist. Did he stay at the scene?? Was he in the lane??
They always mention that the driver was uninjured when they hit a bicycle.
This road is narrow, with 2 foot shoulders and most likely intermittent shade, all make things more dangerous.
Most people would be driving on or near that fog line most of the time. 55 mph is pushing it on that road. But I managed just fine, to not be in an accident on my tour last summer.
