@zane,
Aside from the obvious flaws in CGP Grey’s video about traffic (solution doesn’t fix problem, effectively bans pedestrians, ignores the reality that the better solution already exists) the video that actually made me dismiss him as a credible source of information was his America pox video.
For those who don’t know the story, Grey made a video based entirely on a largely discredited book, and when professional historians pointed this out to him, he said that he did it to mess with them. There are two possibilities, he was lying and would rather lie than admit he made a mistake, or — significantly worse for him — he was telling the truth, and misinformed a large amount of people who trust him because he thought it would be funny.
