I'm sitting in driver's seat of my 4-door mid-sized sedan at an intersection where I want to turn left onto the crossroad. I have a nice clean view of both directions and am ready to make my move when a silver SUV pulls up alongside of me on the right, fully blocking my view of traffic. Apparently the driver felt it necessary to pull up far enough so that they could see in front of me to the left, despite the fact that they could very clearly see above my car.
I realized at that very moment how much that particular situation irks the heck out of me! It happens a lot too. Why people in large cars, vans, or trucks feel that they must be ahead of you to see traffic is beyond me. Most of them sit well above the roof of your car and therefore have a clear view even if they sat back far enough to ensure their vehicle is not blocking your view of traffic. Even if they cannot see above the roof of your car, they can surely see above your trunk.
When I am the one pulling up next to another average sized car turning the other way, I do my best not to block the other driver's view. After all, if you sit back just so, you can see through their windows to the other side thus giving you the necessary view of both directions of traffic. Why can't people figure this out?
