Steady driving on freeway obviously it's not shifting at all unless you are constantly accelerating or decelerating. It is noticeable how in city driving it prefers a really low gear, so it seems like it shifts a lot to get there. This is minimized when in sport mode (DS), because the shifting programming is more aggressive (i.e. higher gear), which I am pretty sure is the only thing that sets "sport mode" apart from normal drive mode.
