I can't believe I need to state the obvious here, but this is over and above all of the other extremely valid objections already raised by others vis-a-vis turning the door you sit right next to into an ersatz Molotov cocktail that weighs an extra fifty pounds.

How is this going to help gas stations become drive "thru?" (I see we still also haven't learned how to spell "through.") It's going to allow the gas station to do what, exactly, stick a nozzle in the side of your car?

That's already how filling a modern car with fuel works.

(Yes, I specified modern because otherwise at least one pedantic nerd is going to go "well acktshully" and mention any of the various cars from the '60s and '70s which had the filler hidden behind the license plate or brake light or an emblem on the trunk lid or whatever. We already know. Nobody cares.)
