You'd have to be blind not to see that he was racing the G Mercedes passing traffic from right side, had to emergency brake when the G slowed down due to traffic and consequently lost control.

You describe it with all of the empirical authority of someone riding in the car, irregardless of the fact that there is no description of the video.
Looks like he regained control fairly expeditiously to me. Hence the absence of car parts scattered randomly all over the highway. In fact, there was hardly a bump when he hit the curb.
I'm not saying he was intentionally parking, but recovering from a skid like that, without crashing, requires a combination of skill, experience and luck.
