For the sake of clarity, it would help if every poster had at least the country they ride in, as part of their personal data (left-hand column), or, failing that, that any post referring to "left" or "right" turns specified "across traffic" or not. Just a suggestion....
I agree with John E. that the woman who rear-ended the Giant bike rider should have been dealt with in court. It hurts cyclists a lot to let motorists get away with actions like that.
"I didn't see you" has got to be the lamest excuse on earth. Just think of all the things you could "not see" while driving: pedestrians, cyclists, children running out into the street to retrieve a ball, and on and on.
If you're not going to SEE, you should not get behind a steering wheel.
