I don't think comparing the size of the voids with the size of the hill as a means to illustrate how small they are is valid.
Quite, this is something of a red herring. Even minor subsidence in a structure can result in major damage. A few cracks in the foundations of Durham Cathedral would be seen as minuscule compared to the total mass of the building - left unchecked they could well be enough to bring down half the structure.
Ok, some rule of thumb maths here.
Let's say a standard 4x4 car (I drive an X-Trail for instance) is 1.8 metres high. It's approx 4 metres long, by 3 wide. I make that a volume of some 21 and a bit CuMtrs.
Multiply by 6 to get a rough figure somewhere near 125 CuMtrs.
That's a lot of space! Hardly a small area...
