Yes it's true that NURBS are used by actual car manufacturers. But those are people who have 10+ years of experience climbing the difficult learning curve for a specialized area of modeling.
For most people it's not practical to take that approach, they need something that doesn't take 10 years to learn how to use.
I find it quite frustrating that there are very few car modeling video tutorials for MOI3D. Yet we see what can be accomplished when in the hands of a very talented modeler like Kuechmeister Swagger. However I am quite perplexed why there is never any audio. I find it rather difficult to have one eye on the screen watching the modeling process and my other eye trying to read the text. Adding an audio track would make the process so much easier to follow and understand.
