I may be missing something here, but I don't see the problem with the newer "tank-ette"s. We have a 2025 Nissan Kicks - sure it's SUV shaped, but it's not tall or have any of the issues typically associated with SUVs (I'm not an expert on these issues - happy to be educated here) - it really is just an SUV shaped car. Where I live there are lots of oversized pickups on the road, but there are also LOTS of Honda Civics and Hyundai Elantras - both still available in the classic sedan configuration.
I'm not trying to say there are not huge issues with the car industry/culture - I just feel this article is exaggerating the issue a little. Or, maybe it's a market by market thing and Civics and Elantras aren't available in the author's market..

They've already tried that - they bought one, pulled it apart to see how it worked and couldn't put it together again. There's a Veritasium video about it.
