I don’t expect random people to know, but the media who’s reporting on it? Yes, I do expect that, and it’s terrible reporting when they get it wrong. It just continues to spread incorrect information, which gets further turned into misinformation.
Also anyone who actually activates it in the car goes through the little how it works and what it’s short falls are. If they didn’t know prior, they’ll know then, just like with boaters who learn how it works and what it’s shortfalls are.
