This is one of those situations where you see someone creep forward but don't think they are stupid enough to actually go.
While driving my 67 Barracuda I had one pull out, see me coming, stop, and start to back up, that is when I locked it up and left a mold of my bumper in his side. Had he kept going I'd clear him in the rear with minimal braking
Few years later in poring rain driving a 73 Barracuda I had a car pull out and stop with his rear in my lane, it was clear and no reason for him. Needless to say I did everything I could pumping and steering to try and clear his rear, didn't happen, needed about 18" more, I spun him 90^, again not even a scratch to my car.
Now as for this, it does appear the oncoming driver did try to steer clear. I'm not sure if these trucks have anti-lock brakes but but at the speed he was going and seeing it from his perspective I'm not sure it would have made a difference.
The location US-97 and W-14 in Washington had a merge lane at the time (2013) and in the video I'd say the oh **** moment was when the oncoming driver was about where the merge lane ends (on the other side) that is 400' from the intersection, that being said here is his perspective in 2013.

And now, maybe they thought eliminating the merge lane may keep people from cutting it close.

Thanks for the video... with sound I heard what could have been my own words watching the stupidity.
