I line up 3 metal modelcars in front of my big van - and I'll crush them to dust under the heavy tires! Each tire has over 700kg/1500lbs of weight - enough to even crush these solid-made collectibles! As I drive over them they get flattened right away - but you can still recognize them as cars. But after running over them repeatedly and grinding the tires on them they turn into little crushed pieces more and more. In the end there's nothing recognizable left of them!
