I do not think neither your claim that you are data driven, nor that Oberklasse segment has been seeing declines over the years hold any water.
As seen from the data presented below, the Oberclasse segment sales (without Model S) were experiencing steady
increase after the crash of 2008, all the way to 2014, where the trend was rather abruptly reversed. Since 2014 sales of Oberclasse segment are in decline which is matched exactly by the growth of the deliveries of Model S.
(the 2016 sales below are based on 9 month sales adjusted to yearly sales based on the 12 month / 9 month ratio of sales in 2015.)
The bottom line is that the Bloomberg chart, and a more comprehensive chart below
are vividly demonstrating the obvious. Tesla is sucking air out of the Oberklasse segment in US. This means that stuffing another type of massage or aroma therapy into the coach propelled by technology from the last century is miserably failing at attracting people able and willing to spend $100k on an a sedan, all the while Model S growing their deliveries in US by about 50% per year, taking whopping 25% of the segment last year, on a way to increase it's share of the pie to a phenomenal 35% this year. The entry level luxury segment is next. The kill shot was not fired yet, but we are awfully close...
EDIT: Updated chart - fixed error for Model S 2016 (9 month) deliveries.
