If I have to use a wake word in the Rivian I would want it to be "Rivian", "truck", or "RJ". Or maybe "Kit" if it was a sports car/adventure car.
That’s actually perfect - I prefer the “hit the button then talk” vs the inevitable execution of a command that I did not (intentionally) say.Not sure if this helps, but the left scroll-wheel button on the wheel activates Alexa without using the wake word—so you could just press that and say your command, no need to say "Alexa" ever.
I would personally prefer the physical in most situations, but I'm also a little paranoid and can't stand cloud-based spyware. So I will most likely be disabling the Amazon integrations completely if there's no on-vehicle voice control.
