I think this boils down to aesthetic preference.No, but that's not a good comparison. Model 3 has the same back as Model S just with stuff removed. That's why it looks like something is missing. The spot I'm pointing out is literally the same exact shape as the metal strip. Seriously?! Maybe it would be a good design if we didn't have Model S to compare it to, but it looks lazy and unfinished as is.
I don't share your feeling at all, and I don't feel that there is anything "missing" or "unfinished" from Model 3's back. Granted, I don't feel that it looks anything special or distinct either, just like most other cars on the road. But it certainly looks fine and complete as is.
As you can see, a metal strip doesn't belong anywhere on the Passat. If it did, it would be huge and ridiculous-looking.
Actually, I would feel the same as applied to the Model 3!
