A Great New Way to Set Your Side Mirrors
Step 1: Start by setting your rear-view mirror as you normally would.
Then,
lean your head all the way to the left so it touches the driver’s window. From that position, set your left side-view mirror so you can see the back corner of your car.
Now lean the same distance the other way, and set your right side-view mirror the same way. Now, here’s what happens. When a car comes up behind you, you should first see it in your rear-view mirror. But as it passes you (let’s say on your left), you’ll see it move to the left side of your rear-view mirror. And as its left headlight disappears from your rear-view mirror, it should instantly show up in your left side-view mirror. There should be no delay. It should slip from one to the other, so you can always see it.
Step 2: Left-Side Mirror Alignment: Set your left-side mirror so that as soon as the passing car's left, front headlight disappears from your rear-view mirror, it appears in your left-side mirror.
You might need to make some slight adjustments to your side-view mirrors to make everything line up perfectly. And pulling up next to a line of parked cars (to simulate another lane of traffic next to you) is a good way to do that.
Step 3: Right-Side Mirror Alignment: Then do the same thing on the right.
Step 4: End result? No huge blind spots. Driving with the mirrors this way takes some getting used to. You have to learn to rely on your rear-view mirror first. And you’ll have to get used to what your side-view mirrors are now looking at. But, the good news is that your blind spot should now be gone!
