Seriously, also aren’t lights supposed to be programmed to move the most traffic throughout the day… Why would people want to make it less efficient.
Edit: went back and watched the video. They aren’t giving preferred treatment to anyone, they just timed the lights so if you go from 1 to the next it should turn green based on speed/distance. I’m not really sure why you would even need the speed sensors, you can just measure the distance and set them…
