It’s kinda funny when you look around and observe. I feel like it’s mostly Japanese brands. The Lexus ES, Camry, Venza, and Miata, but other manufacturers are guilty too like that new Buick CUV and Genesis EV. They all look like different species of fish
Look at the Aptera. The makers didn’t have a real baseline look they wanted to go with, just that it was efficient as possible, so after going through a ton of computer models and tweaking for top efficiency, that’s what they came up with. The Dolphin shape.
