Some of these profiles definitely correlate significantly. In my rearview mirror I'm looking for two things primarily:

1. Big vehicles/Big sideview mirrors
2. Any vehicle that doesn't appear to be moving just a bit more left as it approaches me.

Up front I'm just trying to make eye contact with anyone entering the roadway, any impediments to that is a BIG RED FLAG.

For passing parallel parked cars, I do my best to look through their windshields and into their sideview mirrors for activity and also for front wheels turned toward the roadway. If their wheels aren't turned out they can't pull out.

Speaking of parallel parked cars, I pay particular attention to Full Sized pickup trucks. Those doors are huge and your body, not your front wheel is going to be the crush zone.
