That becomes a harder sell when the Model 3 is actually more expensive to operate, as it is in some places now.
Its not that they are buying to save money vs the economical choices, but it does make a difference relative to their comps (RWD & AWD sport sedans).
You can tax cigarettes all you want, people are still gonna smoke.
