Looked really close to me. If you pause the video, the car tires are still on the outside quarter of that manhole cover, and that cover looks to be less than a foot off the fog line. I'd say the vehicle is just inside of 2-feet from the rider's bars. I see no oncoming traffic to hinder the driver from giving more room, so they're either not paying attention or just don't give a crap.

I get passed like this sometimes, and it's even when I'm out from the line, riding in the passenger's tire track. It's on a certain section of double-lane where drivers try and squeak past me while simultaneously trying not to hit the vehicle on their left.
