Not sure how you can make such claim without a statistically significant survey. If you truly have data to support your claim, I guess I am like OP and not in your "most people" category. I was given a choice, cost was not relevant for me between X and Y, and I chose Y over X (S and 3 was not in consideration list for me). So I wouldn't jump into conclusion that people get Y because of its lower price only.
That said, if X gets refreshed; have a much cleaner interior than it is today, just like Y; and loses those falcon wings, I would trade in MY for the new X easily for larger interior, better acceleration and higher payload capacity. And if that happens, perhaps some other folks would stop liking model X with a cleaner look like model Y. I guess people are just different, independent of their purchasing power.
Because this topic comes up all the time. And it’s extremely rare people prefer one smaller screen over two. It also often comes up under the refresh discussions with comments like I sure home they don’t turn the interior of S/X into a Model 3 with one screen. Both setups could be refined.
Can you a imagine a Roadster with a Model 3/Y like cabin. I can’t. It’s efficient, not sporty, sleek or elegant. I can imagine a single screen that spans the whole dash maybe. Even the higher end competition went with split. Like the Porsche.
Actually they will probably put a HUD in the Roadster and maybe S/X. I’d trade that for the center cluster display.
