Made a short trip today from San Jose to Carmel and back. It's not a range test, I simply decided to see what I can expect on a regular weekend trip. Traffic was light, the weather nice ~80F, no excessive wind, no big change in elevation.

The total distance was 168.4 miles, and overall efficiency 2.9 mi/kWh. I was driving on US-101 at 75 mph for most part. The efficiency was actually pretty good on a smooth road surface, over 3 mi/kWh. I saw the same numbers in both direction, so the wind wasn't a factor. I think people who got poor efficiency numbers were driving on bad pavements. I found GOM (guess-o-meter) to be pretty precise in terms of SoC % for the trip, even somewhat conservative, though distance to empty is always overestimated. That means the navigation planning is reliable, just ignore the distances.

I like the car a lot, very comfortable ride, good suspension, reasonably quiet, lots of power for passing. What I don't like is software. The menus are unintuitive, the fonts are small, you need reading glasses to see. When I was already on the road I found the left mirror looking down, I couldn't remember were the mirror adjustments were, tried to find it while driving and trying not to end in a ditch. After a minute digging through menus I gave up. Found the menu item when arrived to the destination in a surprising place. I wish I could say everything I think about it to the engineer who decided it was a good idea. Things like that should have physical controls, not being hidden in menus. In general, lack of physical controls is a very bad design decision. Also, using a stalk instead of traditional buttons on the wheel for ACC/UHF is a bad decision, the annoying chimes that can't be silenced is another bad decision, not having resume function is a very bad decision.

Overall, I found ACC/UHF to be poor, often disengaging on curves, with some jerky moves. I never felt safe to let it drive hands free. The lane centering was not confident, often drifting to the left. Lane changing is useless, it thinks too much losing opportunities, I was always changing lanes myself. And the fact that the car doesn't automatically adjust speed and doesn't have a resume function makes UHF impractical on anything but straight empty roads.

Bottom line, the car itself is great, efficiency is good, but software is pretty awful. This is the opposite of my previous Mach-E, which had questionable ride quality, making passengers sick, but on the other hand it had pretty good software and physical controls.

I also owned a MME before my Rivian. Do you think the R2 is more efficient?

From what I have seen, it appears to be significantly more efficient even at highway speeds. Which is sort of surprising considering the shape.

I could get 2.7 mi/kWh at 75-79 mph in my MME. This was measured over multiple trips and in good weather (of course).

My MME was 2021 AWD premium. On the same portion of 101 at the same 75mph speed it was showing 2.5-2.6 mi/kWh as far as I remember. On I-5 to Los Angeles, it would show 2.4-2.5 mi/kWh at 80 mph. But I never really trusted the numbers it shown for current trip. Looking at the long term stats, I've got an average 3.1 mi/kWh.

Thanks for summary. Not to be pedantic, but the software isn’t bad from your description, just not intuitive (except for the UHF part). While I agree that not great to put everything in a screen, it does have a learning curve. Also Mach-E software was so-so IMO. I always put Apple CarPlay and called it a day. Based on this, sounds like the R2 would work for me. Good efficiency, comfortable and quiet ride. That matters more to me than using buttons I only touch a handful of times so it works for me. Hopefully you can keep enjoy yours despite what you see as shortcomings.
