I have a theory: Japanese car's have excellent reliability, their interiors and design are lacking. If every car in the world is an EV, which due to their relative simplicity tend to be reliable, what remaining unique selling points does eg a toyota have?

I'd still prefer a more reliable EV to a less reliable one. Not too many good options for a EV minivan in the US (I'll never buy a Chrysler product, and I don't really want a VW).
