Backpedaling - that's what you are attempting to do.
The fact is, the government, as in federal government, is not doing anything to regulate car prices based upon their abilities. Re-read the discussion from the last couple of pages. That was your main discussion point, and you have shown that you are not able to tie your arguments together.
You are advocating a federal restriction on manfacturing and importing specific products based upon their capabilities. Cars do not have that restriction, period.
Since you are unable to show any policy on pricing control, it appears that you see that your argument has been completely and utterly defeated, and only your desperation keeps you going.
