I’m afraid I can’t remember too many episode titles off the top of my head, but you’ve definitely picked two of my favorites in How Hermes Requisitioned His Groove Back and The Problem with Popplers. I can’t remember the plots of your other listings, but I probably love them too.
I’d have to add on The Devil’s Hands are Idle Playthings. Magnificent episode with one of the cleverest titles I can think of.
I like the goal, but imagine the noise pollution with the sky full of whirling blades. Also, incredibly power inefficient.
I think it would be better to let cars and trucks keep doing what they’re best at, and instead make public transport so good that last-mile delivery is the only thing left on the roads.
