I don’t have anything against news explainer Vox, and this video called How Cars Went From Boxy To Curvy looks good and seems well-made. But it’s not. Factually, it’s a complete mess, and it’s worth taking the time to point out why.
I should mention that I started this yesterday, then got sidetracked with another project, and when I got back I saw that my basic points had been made wonderfully on this Oppo post from N2Skylark. It’s great, and covers pretty much everything I was going to, so you should absolutely go read it.
