It can be hard to gauge some of Cage's strength feats, because they really don't follow the laws of physics at all. It doesn't matter how strong he is, he simply isn't heavy enough to realistically do any of the following:

I mean Danny can punch the engine block right out of an armored truck and leave craters in the ground. So, Cage's ass should have been sent flying regardless.
So, it's a complete and utter crapshoot trying to quantify some of his feats.
