It's sort of fascinating the segmentation thing here. They put it into the "premium sedan" segment when considering sales vs. competition. But in the same presentation, you'll see that most (I want to say two-thirds by eyeballing the chart) of the customers buying Teslas are trading in non-premium brands.
I guess it's possible that Tesla is different here, though if it is, doesn't that argue to the brand's strength? It's getting people who wouldn't normally drop $50k on a car to open their purses.
