Akudama Drive is an anime with a cyberpunk city but I don't think it has cyberpunk themes

I've been debating whether or not to recommend Akudama Drive. The anime definitely starts out in your standard cyberpunk city with giant billboards and bright neon lights, but then the majority of the series actually takes place on a train and in the wasteland. That wouldn't immediately disqualify it from being cyberpunk of course, but the show also focuses more on the characters and their interactions than your standard cyberpunk themes.

I wouldn't say this is a "style over substance" anime, even though there is a lot of style, it's just that the substance here is something other than cyberpunk themes in my opinion. The core theme of the anime is really "what does it mean to be a criminal?"

So the anime is well-made, has great animation, and great characters. And it takes place in a cyberpunk city for part of it but in my opinion it doesn't have many cyberpunk themes. For those who've seen it, am I being too harsh? Is it obviously a cyberpunk anime and I'm just being too nit-picky?
