I suspect that an accurate crash report showing the location of impact in
relation to the width of the roadway... and perhaps the condition of the
shoulder and/or right-most section of the roadway would help figure out
what may have happened. The speed of the motorcyclist might be
interesting too. <br><br>

Whether speculation is pointless or has value depends on the goal,
doesn't it? If one is trying to determine what actually happened, I
agree, speculation is pointless (and is arguably inappropriate for this
forum). But if we're trying to construct hypothetical but realistic
situations based as much as possible on speculating about what is likely
to have happened in a real incident in order to discuss what might have
been done to avoid that type of crash, then I think it has value,
especially if we construct all the reasonably likely scenarios and
discuss what might have been done, if anything, to avoid crashes in
each. The latter is what I assume we're doing here; it is what I'm
doing, and will proceed accordingly. <br><br>
I reread your post. I don't think I misunderstood. Here is
your main point, if I'm not mistaken.<br><br>

I don't disagree. I just don't understand the relevance. The
following applies to any hypothetical lane crossing, not necessarily to
actually what happened in this particular tragedy at all: <br><br>
Regardless of whether the cyclist's lane crossing appears smooth or
veering, if an overtaking driver hits him in the process, the cyclist
violated the right-of-way (ROW) of the overtaking motorist. That
is, the cyclist initiated the crossing of the lane without first
establishing right of way to do so. Some cyclists seem to think all
they have to do to establish right of way to cross a lane in a situation
like this is signal. But that's incorrect. You can't just
signal and cut in front of someone who is about to, or is in the process
of, passing you. You have to wait for a sufficiently long gap, or
use negotiation (signal and wait until someone yields ROW to you, by
slowing down to your speed or changing lanes). <br><br>
Back to what actually happened here, I see all speculation falling under
one of these three general possibilities:<br><br>
1) The cyclist was maintaining a straight line and the motorcyclist
either didn't notice him at all (in time anyway) and hit him from behind,
or the motorcyclist passed too closely clipping him, later claiming the
cyclist "veered" in front of him. <br><br>
2) The cyclist moved into the path of the overtaking motorcyclist
(perhaps because he didn't notice the motorcyclist, or maybe because he
mistakenly thought he had the ROW for some reason).<br><br>
3) The motorcyclist was passing too closely AND the cyclist moved left,
but not much (say a foot or two), though enough to get hit/clipped
because the motorcyclist was passing too closely. <br><br>
Can anyone think of any other possibiliites?<br><br>
If (1), then I can't think of anything the cyclist could have done to
avoid this.<br>
If (2), then the crash was arguably largely the fault of the
cyclist. Lesson: always look back with a head turn (learn to do
this without veering) and make sure you have ROW before moving laterally.
<br>
if (3), again, I'm not sure what the cyclist could have done, assuming
his relatively slight lateral adjustment was necessary and
reasonable.<br><br>
