Feds want robotaxis to signal ‘I’m driving’ with

From the editor

Regulators want cars to use cyan lights to signal "self-driving active". It sounds like a great service to first responders, police, and emergency vehicles, but how will regular human drivers respond to the signal? Will they respect AVs' right of way or exploit AVs' inclination toward caution? (No human ego will be cut here...) As always, nothing is as easy as it might seem.
