- The truck driver does have a right to move into his blind spots if he has taken sufficient precautions to ensure that they are safe. This is completely different from "no right" to move into it.
- There is nothing absolving the car with which the truck collides of fault. [In actuality, blind spot collisions tend to be multiple causation with the car stupid enough to hang out in a blind spot sharing fault.]
- If you get hit by a truck and die, you're still dead regardless of who's at fault.
Which, incidentally, is exactly what I've been saying this entire time.
As for your hypothetical shooter, he may not have the right to shoot you, but nobody's going to be stupid enough to tell you that goading him into shooting you is not the wrong thing to do (which is about as far as that analogy is relevant).
