One of the things I really like about the S is that it's "just" a nice car, it pretty much embodies the ultimate in it's class without getting too exotic, on a basic level it's a practical, albeit souped up, family compatible car. The X could be our second car but it's more exotic than practical, preventing one of the most basic uses of an SUV, putting stuff on top of it. How often do we do that? not as much as we'd like, but wow do we value the capability when we go out for a weekend getaway. being able to put things like skis, surf board, kayaks and/or a cargo carrier on top are basic musts for us. The falcon wings are cool, but they make a huge statement, a bit gratuitous for my tastes and are better suited for a sports car like the roadster IMHO, but that's not as important as the fact that we really don't need a solution to the difficulty of accessing the 3rd row of seats in our current SUV... it's just not that big an inconvenience on the occasion that they get used.
What would make us excited for the X would be the extra headroom, the all wheel drive (for winter mountain driving), a fold down split third row like the S but forward facing and regular old dino-style back doors... basically, if we could have something approximating the Toyota Highlander but EV and X-like, we'd put down a reservation tomorrow!
