Have you seen the latest Civic? It's far less conventional looking than past generations. Electric car styling must reflect a desire from the target audience of small city cars, otherwise there wouldn't be a trend towards this aesthetic.
Electric car styling must'nt do anything. The available demographic reaches far past those in cities who want a tiny car. Car manufacturers just need to make cars that look normal so people will buy them for having a car's sake, not because they want to announce their vehicle is electric.
I think this causes them to want to make their Eva look weird.
The Nissan Leaf looks fine for the class of car it's in, but why's it got to be called a leaf.
