you’ve got too much time on your hands. An extremely important engineering term, KISS. A green light up front does not provide valuable information. If you need to spend so much time trying to convince everyone of a good idea, it’s not a good idea.
I see. i disagree and I think that information is not only extremely valuable but extremely desireable. Unlike you, I do not want to know less about what other drivers are doing. And just like I want that information when I am following you, I want it when I am facing you too! I dont know why you would not want that information and i do not know why you would want to hide it from others when an incrediblty over complicated item like a green light sending the incredibly complicated info that your foot just touched the brake. I dont think KISS means what iyou think it means. Why over complicate things with rear brake lights if we can see the vehicle ahead is physically slowing right?
