This isn't a major concern but just possibly a design defect that could potentially be dangerous in an accident. On March 30 2023 I was involved in an accident on a highway in Pennsylvania where traffic was stop and go. I was stopped, and a car slammed into the back of me going pretty fast. Her car bounced off my bumper and then hit into me again. The car and my seat belt did their jobs and I was not injured. However, afterwards the top of my head felt like it had a bad brush burn. It lasted for several days. When sitting in my car directly after the accident I noticed something odd. Both driver and passenger sun visors were off their hooks and in same position of pushed forward towards windshield under the hook. Because it happened to both of them and they were in the same position I have to surmise that the laws of physics during the accident caused this and that the impact knocked them off the hook and the other vehicle bouncing off and then hitting again caused them to pull back and then fly forward. I believe the movement of the visors so fast is what caused the brush burn on my head. I'm not sure if this is generally something that happens during an accident, but it seems pretty dangerous to me. Luckily I am not that tall and was positioned that the visor skimmed the top of my head. I cannot imagine though if someone was taller what that could potentially do if the visor comes flying at someone's face that fast. This has not been reproduced or confirmed by anyone. My v
