I'm really excited to see what will come of this discovery. I will mention OpenTrafficMap [1][2], which leveraged the ESP32-C5 to collect 802.11p V2X communication data (Cooperative Intelligent Transport Systems) from traffic lights, vehicles and other road traffic sensors. This project in particular got me excited about what could be accomplished with these microcontrollers.
