I agree with the radio thing, that was one of my first thoughts when I saw the dash. I’m sure aftermarket will think of something though. It’s not super easy to install a radio on a x3 either, you still need to buy one of a few options in mounting panels or fab one up. They probably didn’t exist either when the x3 first came out.
New models are always a pain at first with aftermarket stuff, also agree there as well. Early adoption of anything new always has challenges. We will just semi agree to disagree on the fuel thing. You want 150 miles, another guy wants 250, most only need 100 at most. For what it’s worth I bet the range on the R is similar to the x3 at 160 miles. Though obviously that depends on terrain and how hard you are driving.
From the pictures and videos I have seen the R has basically the same seat and seat frame and rails as the x3. The existing under seat tanks should fit no problem, at most the brackets may need small modifications. I wouldn’t be surprised If you see R compatible kits pretty quickly.
