Yes, I agree. My point is more akin to addressing why it happens in a somewhat different context than the article which states it's driven by customer subjective taste. I'm saying it can also be driven by something else. There are probably only a few major players in the automotive aerodynamic software design space. Unlike the days when the design was driven by an artist with a block of clay, I suspect modern designs are often based on the same computer driven models with the same underlying physics. The software is probably a more refined and optimized approach, but this results in a convergence in looks and a lack of that idiosyncratic "soul"
