I was watching this video of a live chicken trapped on a moving truck and thought it was strange that it’s not possible to say anything to them even when circumstances might warrant it. All we got is honking and waving. There could be a touchscreen interface with a map of nearby vehicles. It could be voice controllable or the passenger could do it for safety.


You describe contacting the people in nearby cars.
That’s something different than contacting nearby cars.
The latter is developed currently by the car industry. The former has been mentioned: CB radio.
But in both cases: maybe they are not interested in listening to you ;-)
I just want a way to save the chicken :(
