Are the automation features balanced correctly?

I'm just wondering, if Automation features are balanced correctly?
In egnine designer I can can change bore, cam type, cam profile, type of injection, type of intercooler, exhaust size, AFR, size of turbo, and many, many other things. In car designer I can change stiffness of suspension, downforce amount, brake types and size, and also - many other things.
But when it comes to details, I have no posibility to set number of air bags, I can't change ABS ECU generation, I can't set number of car audio speakres or add cd-changer, I can't add navigation system, and many other things that I think I should get possibility to set them in more detailed way.
Engine designer is wery wide, but the further we go, we find less configuration options. I think, that features which were written in the early versions of Automation are more complex, than those written later.
What you think about it?
