according to NHTSA and MSF almost 62% of all motorcycle related highway crashes are from other vehicles pulling out into or backing out into a motorcycles' direction of travel. when you approach a driveway, interesection, or someone approaching you with left turn signal on, NEVER EVER ASSUME they see you. slow down, cover your controls, expect them to turn into your lane of travel or pull out from where they're stopped. what i find myself doing when approaching someone stopped to my left or right and waiting to pull out is watch their front wheel closest to you. if the wheel starts to rotate chances are they are coming out into your lane of travel. once you get the hang of it you'll be amazed how well it works.
