If any of you have used CAD or design programs (Autocad, Microstation, Autodesk etc.) for any products, it takes time to produce the shapes and curvatures, lines etc, especially in 3D and then surface rendering them can produce glitches which requires changes of the design. All this is time and money wasted when you have a tight timeline to design a new product.
Using an AI software to produce a fully rendered 3D image of a car, taking only a few seconds by describing in words what you basically want it to look like, can save designers thousands of manhours. The AI design can be modified and tweaked by the designer in so much less time.
Picture yourself as a car designer in the 1970s in Mercedes design studio with Bruno Sacco. As you can see in the background pic, there is are some 3D designs of a car, that looks quite basic with little rendering but if they had to see what the AI can generate then those designers would be totally shocked from amazement.
Even Mr. Sacco himself would be scared of AI as it can produce designs that could be even more attractive than his masterpieces.
