Um, those are Libertarian ideals, not necessarily Naderish ideals. I would assume that most Libertarians would subscribe to the caveat emptor theory of marketplaces, where car companies could say whatever they want to about their product, but would be judged by the market. (E.g. if GM was caught lying about its vehicles, less people would buy them as opposed to having the goverment legislate a solution).

Not that I agree with either stance, but being pro-consumer is at odds with the Libertarian stance in many instances due to government regulations that (rightly or wrongly) seek to help consumers at the expense of manufacturers.

Naderites might wish to decriminalize drugs, but they sure as hell would want the government to regulate their quality to ensure they were safe. Which sounds reasonable to me...
