Sunglasses At Night

So I'm driving along on a Friday night and I'm trying to drive safely because there are a lot of crazy drivers on the road. The traffic is heavy and I'm driving in a heavily lighted area. The lights from cars and the street lamps are all bothering me and I can not see because the glare is overbearing. I had an idea. At the time the people in the car thought I was crazy. They thought I would not be able to see well enough to drive. Well I was bold enough to put those sunglasses on and guess what. The sunglasses did not help much. The people in my car laughed at me. And here I went into a mindstate of physics to figure out what went wrong. I thought about how the light from the street lamps and the cars were unpolarized light. This means that there is no preferred vibrational direction for the accelerating electrons emmiting the light. Basically the electrons are not vibrating only vertically or only horizontally but rather combinations of both in a lot of directions. I then focused on the concept of glare. I thought glare happens because light comes off on a horizontal plane from horizontal surfaces and vertical from vertical surfaces. That's when it clicked. Even though my polarized sunglasses were acting as polarizers the filters in them were probably vertical. This would block out the glare from the horizontal surfaces but it would not block the glare from the vertical surfaces as the vertically traveling waves still can move easily through a vertical filter. This means whenever I looked at anything through my shades from a vertical surface there was still glare. I took off my shades happy with my conclusion and drove off into the night.
