No no no...I hate that analogy on "luck or skill with the steamroller" thing. Oi it is just terrible.
You got away because of basic common-sense. And physics or something.
Did you miss the part where I said... think abstractly for a second, not literally. A lot of strategies that traders deploy don't see the damn steamroller.(i.e. OptionSellers) They're blind to it. So they think they're just picking up change, almost for free.....
