Agree but it needs to behave like an authoritarian little group - lots of autonomy and decision making abilities.

A lot of car designs are done by a single person aided by a small group of exceptional designers. That brings me to a second point - that team has to be the cream of the crop. Not any goof with design degree but a demonstrated long history of exceptional understanding of human to machine interaction. Apple attracted such people back in the day.

It's still not the same though. There was a lead designer, who was accountable to the CTO, who was accountable to the shareholders. There's downward pressure to stop analysis paralysis when it appears.
