When my Y was at the body shop to fix the trunk lid ding I put on it I drove a Toyota Highlander Platinum 2022 rental car. My impression was the opposite of yours as far as quality of the interior. Nothing special, seemed dated. On the road it was a pig, with a soft suspension that bobbed around on the road, imprecise soft steering, and grossly underpowered; as my wife said it felt like we were "wallowing down the road." Lane keeping needs work as you noted, it ping ponged back and forth between the lines, had to keep it turned off. Entertainment system was rudimentary. Like I told the rental agent when I dropped it off, it got me where I needed to be but I wouldn't ever buy one.
Not directing this at zpaul but I wonder if some of the responses to the interior confuse the simplistic interior with lower quality. A friend of mine who is interested in a Tesla is a "luxury girl" and she likes big, plushy things. She drives only Mercedes SUVs, her furnishings in the house are all big, overstuffed, ornate things. My home is furnished in Scandinavian modern. While my Ekornes furniture cost at least as much or more than her ornate stuff she thinks her furniture is on a different price level. She'll get to ride in my Y for a couple of hours when I drive her to Richmond for a test drive of an X. I suspect the Y wouldn't be plush enough for her, but the new X with air suspension, noise cancelling, and perforated seats will be more her level of comfort.
Edit: The Highlander had paint zits and the panel gaps weren't even.
