I think there are other electric cars out there that are the electric version of a "typical" car.
My theory is automakers want the car to stand out, even if it's ugly, since otherwise how will anyone know you are driving an electric vehicle?
(The electric has a practical range of about 80 to 120 km, i.e. around 100 miles, so not a great success.)
For example, the Tesla 3 pushes the passenger space forward and backwards to fit more people in the same space. It can do so because there's no big, heavy engine up front. Starting with a traditional car body and adding electric is just going to waste space.
Also the most iconic full EV car, Tesla model S, looks very much like combustion engine cars. In fact, from distance it's hard to tell it apart from a Ford Mondeo, the symbol of mediocrity (at least in the UK) which is also a fine and nicely contoured car.
The more distinctly formed EV cars, on the other hand, look about as weird as Granma Duck's 1916 Detroit Electric; they have some futuristic aerodynamics but on the desirability scale, they seem to suck.
The interior is where there's a bunch of new rules in play, with the front mounted ICE being replaced with a floor of batteries and between wheel motors. That directly allows Tesla to be amongst the safest cars ever built, and to fit more passengers, more comfortably than similarly sized ICE cars.
Tesla needs those advantages to balance out initial shortcoming of EV cars, at lower mass-market price points that becomes even more important.
