You should adjust your side view mirrors to the point that you don’t see your car in them. This helps minimize that annoying blind spot. A great way to test if your mirrors are in the right position is to drive in reverse past a car (obviously, don’t do this on a road or in traffic. More like, try this in a parking lot or your driveway), and at the point you no longer see the other car in your side view mirror, you should be able to see the car in your peripherals. And if you can’t see the car in your peripherals, then your mirrors are not in the correct position.
