"A civilian witness’ evidence gives us some sense of this possibility when she recounts that the motorcycle could not be seen in her rear view mirror when she checked it 30 seconds before it passed her at high speed without any warning."
Leaving aside the rest of the post for a minute, I find this quote highly unusual. It has been posted before. The wording and its' inclusion strongly suggests bias due to piling on irrelevant perspective. 30 seconds is a long time and we know he was speeding.
