In Australia (and presumably the rest of the world?), it's never the fault of the driver who was rear ended. Everyone else is expected to maintain a safe distance in case the driver needs to perform an emergency stop. Actually I remember hearing somewhere that Japan uses a 50/50 split for all accidents, without working out who's to blame, to encourage everyone to be more responsible. They'll definitely have to tweak the cars driving styles per region. I'm now actually pessimistic that this will ever leave the USA any time soon, given how long it seems for even simple things to make it out.
