I'm sorry, correcting a story with recent factual information doesn't strike me as undermining the fundamental credibility of a source. Given that they correctly source and attribute the claim that it wasn't tested to a recent article that was accurate at its time of publication.

And given that Tesla did not respond to their request for comment on the data, nor did the national highway safety administraiton, who was supposed to correct them, how?

This is not a problem of bias.
