I had an idea over 20 years ago that was very similar to this – except I had an additional twist – when the car was actively accelerating (ie, gas pedal being pushed and not just coasting) a small segment of the tail light glowed a faint green.
That would give followers the ability to know everything you need to know about the momentum of the vehicle in front of you.
In any case, it is about time we update brake lights.
It’s only taken about a million years, but someone has finally decided that improvements are possible in automobile braking lights. Students from Virginia Tech have developed a new system that can show not just whether you’re stopping, but if you’re slowing down, when you’re about to stop, and how quickly you’re pressing the pedal. The concept uses an array of horizontally arranged LED lights — when you begin to slow, lights in the center glow orange, after a certain threshold side lights turn to red, and if you’re slamming on the brake, they’ll all flash red.
