Your body quantum-tunnels [1]through the car and emerges un scathered on the other side. IANAP, but I believe it is technically possible although the probability is astronomically close to zero. Butif QI is true, you would experience it. It is an example of the apparently logical impossilities that the parent is referring to if I understand correctly.

[1] or fails to interact, or whatever. Again, IANAP.

Yeah, but if consciousness is the invariant, then there are vastly more futures in which I don't tunnel through the car but just barely avoid brain-death.

And when I say vastly, I'm pretty sure the ratio is larger than the number of particles in the universe squared.
