“That’s all you need to know” is not the best way to put it… “It’s one of the best hacks out there” would be better. It’s kind of “take the stairs instead of the elevator” on steroids… you’re modifying something you have to do anyway, creating a new habit that will work in your favour… and in this case it also has environmental benefits and is likely cheaper then other forms of transport. But like any hack, there are scenarios where it won’t work, that’s clear.

Recumbents are great for all body types.

What about the type that has bad knees, or metabolic issues, or low vision, or seizures, or about a hundred other things? Somehow I think a hard-to-see-in-traffic recumbent bicycle isn't going to be a solution for them. Advocacy is a wonderful thing, but when it turns into ableism it's disgusting.

I hear you. My uncle is disabled in the legs and I’ve admittedly had a hard time finding a recumbent arm bike that he felt comfortable enough to actually do his commuting on.
