Because Lemmy does not replace Reddit for me -- but rather, it's a different thing altogether.

The Not Just Bikes guy absolutely understands that the need for most cars disappears once city planning is done properly. The whole message, the very thesis of his entire YouTube channel is all about exactly this. His series on Strong Towns is a good example of this.

He knows what the important issues are. This is just one video where he demonstrates in detail that the detrimental design of SUVs in the US is just one part of the overall picture. That's why the video matters! The planning of cities is, among other things, tied to the willingness to accommodate huge, wasteful vehicles.

The sheer fact that he is calling out this trend -- his willingness to point fingers at the auto industry for manufacturing a nationwide desire (or a misguided "need") for bigger, heavier vehicles -- that's what makes it NOT an American perspective.

This is the right answer. I certainly wouldn't say that Lemmy is "for" programmers, but it attracts a certain kind of audience, doesn't it.
