Your experience in your first example is not dissimilar to my various experiences with Lyft and Uber. A Lyft driver was incapable of following my directions at SFO (I followed the Lyft instructions). And I've had Uber drivers basically accept my request, only to remain in one place for 15 mins despite being 3 mins away (happened once in South America, another time in Canada). I've also had Uber drivers who enter in the destination only to get flummoxed by the map and basically go rogue.
