I did...it went from 65, to 64 just before impact. Do you know how big rig brakes work? Even if he hit the emergency brakes, it isn't an instant application of the brakes.
I have 20 years of driving on ice slick as ice rink. I used to play ice hockey so I know ice.
That rig knew that car was going strange. So moved towards the right. Speed stamp can also be delayed even so, speed doesn’t show drop until after impact.
My guess on a rigs bracking ability is gonna be like a be 4x4 on ice. The bigger, the longer the slide. Tiny dinky cars within the 400cc group stop amazingly fast on ice. So, the momentum of that rig obviously won’t be able get anywhere near to stopping in time. The driver should have been slowing down before the “lane change”.
Emergency break? If on a rig is like a car, won’t help at all and I could see the truck jack knifing. I guessing but a car’s emergency break is like 40% power of normal break application. Which is why you use it in ice to drift :-)
I am thinking that rig driver thought he could pass on the right but hit a “oh shit moment”. Dallas is full of oh shit moments so I drive more defensively than normal.

No, I have never driven a big rig.

A big rig's "emergency" brake releases the air pressure and allows a spring to engage the brake.
Here's a good video explaining big rig brakes - https://hooktube.com/watch?v=3mrUMTP4thI
IMO, it looks like the car's rebound from initial impact caught him out and at that point he was a passenger because he's committed.
