In the case of my bicycle accident, I think I probably would have been
flattened rather than just struck a glancing blow, had I been further
out from the kerb. I had already pulled over to let a car overtake me
perfectly safely with lots of clearance, but I suspect that the truck
driver wasn't concentrating for some reason. It turned out that he had
an appalling accident record.

Or, p'raps, you'd have been more visible to him and the collision
wouldn't have happened at all?

Impossible to say.

While you can say that had the offending vehicle had the same
trajectory/position you'd have been hit more squarely, as I've pointed
out several times had you been further out it would have had a very good
chance of altering the driver's perception of what would be safe to attempt.

On the other hand, if he hadn't seen me, my chances of surviving the
subsequent collision would have been enhanced by wearing a cycle
helmet.

Again, impossible to say with any objective certainty, even at the level
of saying it would improve your odds.
