As an AW user I can definitely see advantages to not having to pull out my phone. Here's a non-Rivian real world example...I have a "smart" garage door that includes an iPhone app. This is great for when I'm shoveling snow, in that I can come out of the garage with my shovel/snowblower and close the door with my phone to keep heat in the house, then open it again when I'm done and ready to go in. HOWEVER it doesn't have an Apple Watch app. Which means i have to dig out my phone from layers of coats and clothing. It would be so much easier to just look at (or, preferrably, tell) my watch to open the door.
