The major form is just a generic small city car, which is clearly the target market for this design. The short wheelbase combined with maximized passenger compartment leaves little room for any other form, whether electric or ICE. As others have mentioned, it looks similar to many other subcompact economy cars.
The minor styling to me is not just retro but references the low-budget street racer scene. Flat shading and almost shaved appearance, not unlike second hand cars I would see among teenagers and twenty-somethings, stripped of their OEM trim to cleanse it of the stuffy practicality of its original owners.
I think this is why some people react to the design as 'alien'; it looks almost like an old Golf, but then things like the curved hood and the rounded corners on the headlight/grill assembly push it over into the Uncanny Valley.
I think this is going to be a problem for the Audi e-tron. It looks just like a Q3/Q5. I'm not sure I'd recognize it on the road.
A very interesting theory I had not heard. I love Honda. My jaw dropped when I saw that design. Maybe in 5 years :)
