Many people I know who are giving directions as I am driving tend to say things like: "I meant to tell you to turn back there (pointing out the rear view window) :-) I think that the problem lies in someone's ability to provide directions in enough time for the driver to react. Many times if we are not completely familiar with the path we are traversing, the direction givers must first get themselves oriented properly and look for the right place to turn. It is not simply a matter of saying "right" or "left", but also where to make the turn. Everything is further complicated if we are dealing with multiple lanes that require the driver to be in the appropriate lane to make a turn!!!! -- George W.
