Seems a big part of this is Tesla's minimal and globally available product line (which I commend them for). Other automakers produce a huge number of variants within and between markets. That dilutes the sales of any single model.
In fact for Toyota there are some 15+ Toyota SKUs and 15+ Lexus SKUs - ranging in price from the Corolla (compact) to the Sienna (minivan) to the BRZ (youth sports car) to the BZ4X (CUV EV) to the LS500 (executive sedan) to the Landcruiser (guerrilla infantry vehicle).
