Since this thread is already derailed beyond rescue… 
First, car bodies are not the only products that would benefit from more surface tools.
Second, I’d prefer that someone develop robust filleting tools (and drafting) tools so we can get the last 10% as well.
What @Rhino_Bulgaria does more or less manually in Rhino is extremely impressive, but utter insanity. If he’d learned Alias years ago, the sad truth is that he’d be orders of magnitudes faster at his job today (sorry, but I think the multitudes of customers complaining about Rhino’s poor tools are evidence enough of this matter… Rhino is amazing for roughing out surfaces, but those last 10% take ages… in fact, correct me if I’m wrong but I believe @Rhino_Bulgaria is somewhat of a Unicorn!).
