Why the sugar would anyone think heated/cooled cup holders are useful? 90% of our travel mugs now are double walled and/or insulated, so all it does is warm or cool the outside of the cup.(seriously, Yeti mugs will keep your beverages hot or ice cold for hours...)
Excessive cup holders are such a weird fetish...
I remember the criticism Tesla had early on when they refused to play that particular game...
(edit: and to keep it connected to the thread, this is an example of how Tesla looks at things buyers say they want vs what they actually use/need - cut costs via skimming off the stuff 95% of customers don't actually use, that 5% will complain loudly, but the 95% really don't care - while legacy has tended to try to please every customer's demand... Like the CD players Tesla refused to add even though everyone else still put them in - every penny of savings adds up)
