Interior layouts have come a long ways, especially with EV designs where the geometry isn't constrained as much. As a big guy, the actual space I'm sitting in is more roomy and comfortable on many subcompacts than full sized cars used to be. Since people have gotten taller, there's also more emphasis on leg room. I remember big 1970s cars where the drivers seat just wouldn't go back far enough for me, whereas even the smallest subcompact modern cars do.
