I don't agree that "this reduces the rear driver's cognition of those signals." No matter how close you drive to the car ahead of you, it's still ahead of you, and the driver's side rear light is always nearly directly ahead of the following driver's seating position.Yes the center brake light is useful. Particularly for dense urban traffic. Drivers tend to be more focused on what is ahead of them. As the distance closes between drivers, the front car's side taillights move toward drivers peripheral. This reduces the rear driver's cognition of those signals. The center tail light helps rear driver's maintain a clear visual in their main sight line of what the lead car is doing.
That is why they reduce rear collisions and became mandated.
The one situation where I think the third light would help is if you have a Super Duty tailgating a Miata so closely that it can't see the taillights. This is an inherently unsafe situation regardless, and already against the law, so isn't enough by itself to justify the third light.
Without looking it up, I feel safe predicting that when these laws were passed, they were lobbied for by companies that make automobile light fixtures, and passed by politicians who wanted to be seen doing something, or were in on the take.
