The best advice is expect the unexpected. Expect drivers to pull out in front of you, change into your lane, or anything else.
Also, IMO, stay off the rear brake and if you do use it, practice using both under sudden stops. I see so many people get into bad situations and hit the rear brake in panic. I think the throttle can get you out of more tight spots than the brakes ever can. I'm sure some disagree but that's the way I see it.
