Vending machine for cars. This "sexy" appeal is still on display in some cities as the silo of cars with floor to ceiling windows. The novelty may have worn off, but it is still a more efficient way to display "for sale" cars used/new so much that I could see Costco putting one up. The battleground here is in part what cars will be ALLOWED to be driven and what role will Carvana need to adhere to as the climate change debate and gas prices, and all things with car ownership battle with shared (self-driving) transportation.
