Either he meant to hit her or he screwed up. There's no third option.

Doesn't matter how fast it's going, only whether you're getting closer

We do know. But the prosecutor would _love_ to have you on the jury.
There should be a test for common sense.

You didn't give any devils advocate responses though, just showed that
you can't see a car in front of you, then backed down when nobody agreed
with you.

Which makes the rider no less an example of Darwin at work.

No, the motor vehicle that you hit will.

The only additional information required is knowing that she was
stopped. Given that, it's clear that the collision happend SOLELY
due to the motion of the motorcycle, and if the rider couldn't stop
or otherwise avoid that collision then it's perfectly clear that he was
outrunning his sight distance. That's sort of the definition, you know.
