Korea 's hyundai cars is selling very well now.
If you are very strong in solid state, most likely you can make cars like US, japan, germany and Korea.
But not the other way around, if you know how to make cars , doesn't mean you are good at solid state.
What make you say that? Just because you have good solid state technology, you can make good cars?
South Korea's ability to built okay cars not because they have good solid state technology. I have emphasis before, and I will emphasis again... these two are different industry!
The only thing that I can think of is that South Korea had good electronic background, so they are using electronic system in their car to improve fuel efficiency, etc. And that is about all there is.
