Your chronology is screwed up, we didn’t hit mass market until the model 3.
The litmus test is what cars you see on the roads of Wyoming. There are plenty of model 3s, and a leaf was an extremely rare site because the car was nearly useless outside of a city commute.

Given that US adoption of electric cars lagged other developed world countries, and thus early electric cars were generally designed for European, Chinese, and to some extent Japanese, market preferences, that seems like an extremely weird litmus test. Tesla _was_ the first company to release a mass-market car aimed at the _US_ market (or at least the first credible attempt; the Leaf was available in the US but was just too far from US market preferences), but the Chinese and European markets already had mass-market electric cars.
