My bet: The features not been fully completed, just roughed out. I think this happened early when Uber announced pool (the day before lyft), for a short while no-one shared and you just got a cheaper ride (lyft had actual sharing from launch). Obviously it was worth Uber fleshing out sharing asap, but maybe it just isn't with surge-notify. If hardly anyone is taking advantage of it... just having a delay of a few minutes may mean that most users impatiently go with the surge.
