I agree with StellarsJay's comment, the shadows are useful if you can see shadows. Howde's comment on the use of GPS and quick lane changes is spot on. I've never used the back-up camera for this purpose. I can see the side of my coach in the right hand mirror (just the edge), when the distance beyond the coach to the vehicle I just passed is equal to the length of my coach or greater, then I am clear to pull back in after passing.
I have two comments on passing. On two lane roads, I try to pass only those vehicles that are traveling seriously slower than I am. I lay back a fair distance and wait for my chance. If I can get a good clear distance ahead I'll accelerate in my lane building up speed watching for new oncoming traffic. Then, when I am approaching the vehicle I want to pass I will take the passing lane and continue accelerating on past that vehicle. This allows me to quickly clear the vehicle I am passing and minimizes my time in the passing lane.
On three lane or more urban highways, I drive the second lane from the right and try to keep up with traffic. This keeps the entry/exit lane open for that traffic and I don't have to be constantly changing lanes to pass slower entering or exiting traffic. When I pass those slower vehicles I will stay in the center lane. This is good driving practice and if you watch the big trucks, it is also the way they drive in urban traffic. When the GPS indicates a coming turn then I'll move to the turn lane which is usually a single lane change. On occasion when a truck comes up behind me I'll look for a clear space in the right hand lane and pull over to allow them to pass me then move back into the center lane when space permits. If this works right, you really don't do all the risky lane changes of a standard passing movement very often.
