Fred McNabb illustrated an idealistic series of futuristic concepts for the New Departure Manufacturing Company, founded in Bristol, Connecticut by innovators Albert and Edward Rockwell in 1901. By the way, Albert was also the founder of the Yellow Taxicab Company of New York. New Departure later became a division of General Motors.
The above 1956 illustration seems to have numerous details that are mystifying, at the very least, like the conveyor belt for sending out groceries on a rainy day. I cannot imagine this concept succeeding east of the Rocky Mountains in the winter. Plus loading the preferred brands one is there to purchase. They did seem to envision the drivers' ability to open the trunk from inside the 1959 models, however. Not being able to comprehend there will be more than seven shoppers at a time is a huge oversight. Let alone the idling cars behind as if at a McDonald's drive-up window. Optimistically, perhaps these were the "express lanes" when shopping for no more than twenty items. One had to shop inside the store for a full shopping experience. Without ever knowing it, it seems the bazaar illustration was heading in the right direction regarding "remote" buying. What McNabb and New Departure could not have possibly envisioned was the Internet. Or shutting down the economy in 2020. Shopping without ever meeting any live person has become common for those who experience "life" via a Smartphone.
