Summarizing the requests in buckets of must haves, luxury optionsMy only *must have* feature is Apple CarPlay. I don't even touch the iDrive system on my current car. It just loads up CarPlay wirelessly when I start, and I don't ever leave it. Waze, Google Maps, etc, but also better voice integration and most importantly better Apple Music integration. I am not switching to Spotify, and having bluetooth as the only option is a big step backwards. Preferably Rivian would implement it wirelessly as well, but even if wired is the only option it really needs to be there.
Nice-to-haves would be massaging front seats and a heads-up display (use both all the time), ventilated rear seats, more granular seat controls (thigh support, bolsters, headrests), rear-seat sunshades (power preferred), frunk-grille cut-out (F-150 Lightning style), power rear-glass (Tundra/4Runner style), and removable top (which is allegedly coming).
Also, I wouldn't mind an actual glovebox. Still haven't really seen an explanation for why that's missing...
