RRFBs. HAWK signals. Do any of these devices actually do what they’re supposed to do, and how do traffic engineers decide when and where to install them?

As a European, much of this was mind-boggling to me. While I believe all of this is real, I still found myself wondering throughout the video: Is this actually the norm in the US, or are these some cherry-picked bad examples? It felt for me like a whole other level of systemic hostility.
