I agree that convergence is soullessness, both on the part of the producer and consumer who is choosing the default or merely practical. That's fine for those who only see cars as a means of transportation. A 'better looking' (according to those 'with taste') shape of a car doesn't have to cost more intrinsically. The reason we have many similar, not so great looking cars is because it's not a primary filter for sales volume. Something that paints outside convergent lines, is however a reason why a potential buyer would not buy it.

Poor quality can give a car a kind of personality, but that's not the soul of it. The same car could be reliable and have the same soul. The main difference is whether it is developed to a specific vision, or if checking boxes and aggregated by committee.
