What are some commonly known facts that are too bizarre for you to believe to be true? (lemm.ee)

For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some 'organic element' since I couldn't accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.

So basically because you have more than enough rpms to maintain idling the engine knows to turn off fuel injection until it needs to exert force again?

I'm thinking of a scenario when you start on a level road, reach a slope going downhill, then reach a level road again. Then the engine first consumes fuel, then it shuts it off, then eventually on again, without me pressing the gas pedal at any point?

yeah, exactly. I don't know enough about the implementation details to know if it is actually consuming 0 fuel though but there's not much work the engine is actually doing.

Great, this explains everything, thank you
