Another unpopular opinion but I can't see many people choosing a Model 3 over the Model Y.
Sitting in a Y, I found it superior in all practical aspects. As I predicted years ago, the Model 3 annihilated the Model S. The Y will finish off the S/X and even cannibalize the 3.
That's ok though for Tesla as they are undoubtedly building higher margins into the Y.
From what I know about Tesla's activities is they are adding more production capacity in Fremont. The 3/Y share roughly 75% of the same components, so I am sure all that is needing is a finishing line.
I expect Tesla to produce the 3s at same numbers while building up the Y. At some point, the Y takes over the lions share of resources.
