What is the solution to tunnel vision and blind spots? Simply adjust the side-view mirrors just beyond the point where you could see the side of the car on the inside edge of the mirror. With this setup, you almost completely solve the blind spot problem. To adjust the outside mirrors this way, follow these two steps (This of course, is for vehicles with an inside mirror): For the driver side mirror, roll up the window and press your head against the glass. Adjust the mirror so that you can just see the edge of the car. For the passenger side mirror, place your head in the center of the car (directly behind the inside mirror mount) and adjust the outside mirror so that you can just see the edge of the car. This is necessary even with convex (curved) mirrors where the image is distorted a little. When you’re in your normal driving position, you won’t be able to see the sides of the car but will be able to see other vehicles in the adjacent lanes. For those times where there is a vehicle present in the other lane that isn’t visible when checking the mirrors, the other vehicle’s position will probably be such that its front is adjacent to your door and you’ll spot it in your peripheral vision as you check the side-view mirror. Most of us have dealt with blind spots by turning our head for a quick check. This isn’t generally a problem in terms of missing something ahead; however, there can be a dangerous side effect. - See more at:
