"Cathedral of speed" is just an analogy. If I say that a book contains a tonne of information then it's clear I don't mean 1000kg (but I'm still referring to that definition). If I say my builder delivered a tonne of bricks, but really I just mean quite a lot, then that's confusing. (I do disagree with the GP comment though as maybe this guy was trying to build an actual cathedral. But there's no quote in the article that really indicates either way.)
