<< Actually, that's a very good question... why didn't they sound the horn or try to brake? Perhaps they were asleep at the wheel? Lets use this hypothetical example, if a drunk passed out on the road, and the driver of an 18 wheel rig fell asleep, and ran the guy over, who's held accountable? The drunk? The driver? Or both? >>
They did brake, like they said, they were to busy braking that they forgot to sound the horn.
