I love all of those ideas, but I would add one thing: make the tailgate ramp motorized. Watching them take it out and stow it in the demo makes it seem clunky and not easy for some owners. With a truck so feature rich and futuristic, you'd think this would be standard.
Living in the Northeast, I would love to see a CyberSled (snowmobile) than a quad. Maybe by late 2021 they'll get there and offer it as an add-on, like the color wrap.
