Perfect!

every city in the world needs this

Uhhh, no? This is the worst thing possible.

First, it WILL be very problematic for colorblind people. Like, guy drives as a first car, nothing in front and is by these things: “Uhh, is it go or stop?” On normal ones they can see at least which three of the lights is turned on, here it’s all on the same panel.

Second, the yellow thing is both for stop and ready to go. Nomal traffic lights have yellow only for stop, and RED + YELLOW to go. That is a huge difference! Imagine same situation as previously, you are first car, nothing before you, then you look and see yellow on these lights. What do you do, stop or go? You HAVE to stop since you don’t know what’s coming. With the original one, you see red+yellow you keep going, you see only yellow - stop.
