I think you missed the "when correctly used" part. Clearly, the person who hit you was not correctly using the system which places the whole responsibility of this situation onto them. When obeying all rules of the road, situations where rear-ending someone is probable should not arise. The systemic failure here is expecting people not to phase out and pay less attention to the road when driving for hours at high speed on monotonous highways.
