Shine a light on wall 100' away. Put a black dog in front of that wall. Is that a shadow or a dog? Does it move proportionally as the direction you're heading? Sure, why couldn't it?I’ve only had the car for 1,024 days but I haven’t experienced anything that made me think something was moving in front of me due to the dark spots. It does “move” but it’s directly proportional to the movement of the lights.
Wouldn’t an animal be light up by the lights though? They are powerful and a critter would be illuminated. Not dark.
Here's the thing: now that I know what it is, I'm not so concerned but it caught my attention.
