I agree with you about the boring shoe look. Front grills and, to a lesser extant, rear profiles are about the only differentiation.
I call it the Toaster Effect. Most people want a toaster. It just sits unobtrusively until it’s needed, works every time without fuss, and eventually just gets tossed out when it malfunctions seriously. No thrills or romance.
That said, we live in a golden age of cars that are fast, comfortable, safe and trouble-free.
