It's very biased, but they often have audio, video, photos, or scanned public records to back up the factual portion of the story. It's probably safe to believe that traffic light cycles have been shortened, people have been injured post-shortening (though perhaps not because of it), and the subject of the article has been attacking the automated ticketing hardware in protest. Aside from that, it's all about stirring up visibility and support for the guy.

Article suggests his effort have been kept out of the mainstream news out of corporate malice, but it's probably just because a single-person protest isn't very newsworthy until there is a hospitalization or an arrest.

They seem to have the preserved the report mentioned in the article here:

Go to page 13 of the report and it seems quite clear that they have increased.

Zero. Read the rest of the site. These are paranoid ramblings of mostly one individual. The fact that this is on the front page of hacker news really makes me worry about the critical thinking skills of the forum.
