My guess is that half the people there are trying to build a good car and the other half are trying to build a car to a sheet of specs handed to them from the non-engineering guys.
You bring up a good point. 👍 One reason American cars are at times not designed as well as European and Japanese cars is because of this. They have a lot of designers and the more people you have making the choices the more people you are going to have disagreeing. That is why sometime American cars seem to have odd designs or seem like they could be easily made better in some ways. One group of people want one thing, another group wants something else, and then another group wants something totally different.
