When I was a kid and the first stage of the Sydney Newcastle expressway was under construction a bulldozer dislodged a large boulder that rolled down the slope and over a cliff, then fell on a car from a great height. Doesn't bear thinking about really. About the only thing one can say is that the two guys in the car never knew what hit them.
My brother used to comment on the signs "FALLING ROCKS - DO NOT STOP" he used to ask if they went right through to China
