Yes, but their point is that concept cars are just that, concepts, they're not designed for production or regs so the version we get is usually way more bland than the concept. There are a few exceptions where the vision of the concept car makes it into production, but 95% of the time the real thing is bland af.

This does not apply to limited production cars that don't get redesigned to come off an assembly line making 5 other models, such as very expensive cars, loss-making models produced for homogulation, fleet regulations, or flexing purposes
