Hi Shaz,
My reply seems to have not sent. Forgive me if this appears twice:
You are describing exactly the same experience I have from time to time, always at intersections. I have no explanation for it, and have never come across anyone else who has EVER MENTIONED IT, let alone described it so perfectly as you have. I don't just see grey or black auras, I also see silver as well as white ones. They seem to be totally random. The time of day, position of the sun, color, speed or direction of the car seem to have no bearing on the situation, and one car can have a black aura, while the next on can be white. I used to think it was the same phenomenon that occurs when watching an old movie, where the film emulsion breaks down and the light leaks out around shapes and images causing a white aura. I thought is was just glare or light bouncing off of cars, however, that would not explain the existence of deep black auras as well as bright white ones. I also have seen them shoot off the bottoms of cars, so that wouldn't be due to glare. Some cars have the auras coming from only the back of the roof, some from only the front, and some from the front and back. The auras are not like a uniform glow; they are angular and shoot diagonally from the car. Also, ten cars can pass by and all, a few, or none of them will have an aura. I can stare directly at them and they don't disappear. I don't know what I am seeing. This is also without contact lenses or glasses, BTW.
I have no explanation, but am happy to find that someone else sees them, too.
Lisa
