My cousin told me when he enter his car, he put the key to ignition then count to 3 and start the engine.
The main reason of him doing that is to give enough time to fluids (I'm not sure which one) to fill to the engine (I'm skeptic, need more info on this).
He told me that in "ze good ol'days", car would sometimes fail to start if you directly turn the key to start engine and that even if they does start now, it is still better for the engine to wait a few seconds.
This seems logical (although I doubt it's really something we should matter).
Why is it better to wait a few seconds at ignition position before starting the engine?
