It depends on so many different things like how fast one was going, the place that was hit, front, side or behind and what type of vehicle. Certain cars do better than others in crashes or was a motorcycle one of the ones involved?
In an accident who would usually have the most damage? The person who got hit or the person who hit the other car?
Hard to say.
Without narrowing it down to types, vehicles and force diagrams, etc., that's like trying to give make sense of the answer to "What is the average temperature of any location on the earth?"
The "mean" is not representative of the whole because of the 'variance' of the data.
