The Model 3 and Y make that (mostly) moot (size aside).

We've got a Model 3, I've had S loaners and my dad's got an S, and I've driven the S as far back as maybe 2013?

There are things I like about both. It's not at all clear to me that if you made me choose a free car to receive, that I'd choose the S over the 3.

If you're making me spend my own dollars, 3 all day. I just don't like the S twice as much.

Musk said a few conference calls ago that Tesla doesn't really have a long-term ambition to make a significant fraction of their profits from S/X. I believe he said "keeping them around for sentimental reasons", which is probably overstating it a bit.

But they're clearly not worried about cannibalizing their own product line.
