There's still the matter of all the owner's crap in the car, and current EVs would need nearly as much engineering as ICE vehicles to sit vertically anyway.
For example, the Model S still has brake fluid, washer fluid, coolant, and transmission oil, all which are stored in conventional automotive containers and which would absolutely perform abnormally if the car were raised to vertical.
I also suspect the transaxle has open breathers which would drain oil in the vertical position.
EVs do contain far fewer moving parts and reduce drivetrain complexity over ICE cars, but in every production EV design I've seen you only save one fluid (engine oil). Tesla just hide the car's fluids from their owners by putting plastic covers over everything but the washer fluid and then demanding you take the car to an "annual service."
