"Black" credit cards are now a higher level than "platinum" cards, I'd be happy to use my Tesla key card as a (no fee) credit card to eliminate a card in my wallet. Seems like a missed opportunity for Tesla to have a branded card and it's associated revenue. Now it is just in the way of my Costco credit card in my wallet. Instead of airline miles, you could earn supercharger credits or over the air upgrades. What do you think? Also if you are an intellectual property attorney is there any way I can monetize this or is it too late already?
