One thing I've noticed about the SF deployment is that it's slowly gotten better at this. At first it was very cautious about where it would pick you up/drop you off, but now it offers much closer options (from a menu -- a bit like Uber at airports). I suspect this might be something that is human-added from data collected in past trips.
