<I've been living in Belgium for the last 4 years and feel 100% converted to driving on the right - so why did I swerve to the wrong way recently?> You're looking at it wrong. You swerved the right way- if they will persist in Europe, along with the Americans, at driving on the wrong side of the road, then it's their fault. You were on the right side of the road (which is the left side), they were all on the wrong side. They'll come around one day.
Pilots having to make large movements on the controls will always have an idea of their speed and the relative safety of large control inputs. Nobody at high speed is going to slam full deflection on unless absolutely essential. Full deflection of the pedal will not produce full design deflection of the control.
