Seems more a matter of the fates deciding his time was up - he came around a turn, driving in a normal manner on his side of the road, to face an unexpected crash sliding *across* his lane. I doubt many of us would have been able to avoid contact, no matter what evasive action was taken.
If you keep every part of your bike a full four feet away from the center line in left-hand curves (in America and other right-side driving locations), you've got way more reaction time, i.e. time from first sighting of any hazard coming from the other lane. By way more, I mean like double!

There's two factors at play here to get you this doubling of reaction time: 1) the physical distance from the other person's vehicle is increased (from the point of first possible sighting); 2) the additional sight-line around the corner gives more reaction time also.

Average human time is 250 milliseconds (yeah, I know, we're all above average here). 30 mph is ~45 feet per second. That means 12 feet of distance (at 30mph) is used before any reaction even starts, that's distance used before starting to brake or swerve, no braking or swerving actually achieved in that 12 feet of travel.

After 35+ years of daily commuting plus quite a few long trips, I can attest to the dramatic reduction in close calls that comes about from keeping your distance from the blind spots caused by turns. But you can find out for yourself, just try a few corners yourself, pretend that the next car you see is in a turn is over the line and that you've got to move over to make room. See how long that takes.

But that's staying away from the center line is on left turns only! On right turns, I'm way up near the center line, just to get the extra sight distance around the corner, that extra sight is reaction time.

Same difference no? Far right in lefthanders. Far left in right handers. I think David Hough had a name for it.

It is against the law for police to release crime scene photos. Flip it around, someone could have died in that accident. 1500lbs of motorcycle sliding around can do some damage. So, it's you, you are hurt, maybe dead (broken ribs can do a lot of internal damage). And your pictures end up on the internet because some unscrupulous photog thinks they entertaining. And your kids, or your widow, or your parents see it. Welcome to the internet.
I really think you should stop looking at this thread; you clearly do NOT belong here.
