Step 1 set your rear view mirror centered on the rear glass.
Step 2 see what object you can see on the furthest left edge of the rear view mirror. Then position the left side mirror to where the right side of it barely sees the same object as the left side of the rear view.
Step 3. Repeat step two but with the right mirror and the right edge of the rear view.
When done correctly A. you won’t see down the side of your car in the side mirrors and B. a car in your rear view mirror can move to either lane beside you, and as it pulls alongside you and passes you and it will move to be in both the rear view and a side mirror then just a side mirror, then just before it leaves the side mirror it will appear in your side window, therefore you’ll always have some part of the car in either one or two of your mirrors and/or the side window.
This works in reverse for you passing a car. But the point remains there will be nowhere in 360° around your vehicle a car can be that you can’t see some part of it to know it’s there.
And yes if you’re used to gun sighting your side mirrors it may be a bit disorienting at first to not see your car in the mirror.
If you’re in a vehicle that you can’t use the rearview mirror, then lean your head against the driver window, and gun sight the drivers side mirror, then lean your head to the center of the vehicle and gun sight the passenger side mirror, this will give you a look into the lanes beside you all the time while still allowing you to see directly behind you (which is the least useful information while driving IMO) by just leaning your head a bit. Your mirrors should be “timed” so that a car leaving your side mirror instantly appears in your side window.
Remember blindspots behind you don’t really affect you but blindspots in the lane next to you affect you when changing lanes.

It is easier to put your head against the window and move the mirror so that you just see the edge of the car and put your head over the center console and do the same for the other side. It absolutely boggles my mind that 95% or more people set their side mirrors wrong. How do I know? I can see all your damn faces in the side mirrors when I'm behind you. You should always still check your blind spot when you change lanes. Extra safety is good, some cars still have a bit of a blind spot, and a car can easily move from your rear to your side mirror in the time it takes to check them.
