i discovered the reason why everybody turns left after playing rof

[WTE_Galway]

... actually when landing a 172 I have my left hand on the yoke and right hand on the throttle.

More to the point, many or even most GA aircraft have a yoke with a central throttle quadrant, nearly all twins do and most commercial aircraft do.

Hence, most non-military aircraft are flown with the left hand with the right hand on the throttle.
