CLEARANCE

When driving, you should always leave yourself enough clearance. What does this mean? There should be at least a door width when passing parked vehicles. If the door of a parked vehicle opens and you feel a need to swerve, wherever you swerve to, is where you should have been positioned. The oncoming vehicle is not going to open their door anymore than you are likely to open your door while you are driving along, but the parked vehicle is much more likely to open theirs.
