I think the key point here is that Tesla is not trying to make the world's best electric car, they're trying to make the best car, period. If they try to make something radical and different looking, then they're going to gain some extra traction with people who want to stand out and be different, but they already have those people in the bag anyway.
On the flip side, making their cars deliberately strange looking is likely to turn a lot of people off. People who might otherwise be interested in buying a Tesla simply because it's a high-quality, practical car that competes well with other cars in its price segment, gasoline or not.
