I see it as a couple of small sedans speeding for miles (assumed) and weaving in and out of traffic to do so, even though it's highly congested,
with 18-wheelers in both lanes. That's when you know it's highly congested, otherwise the truck would fall in behind the other truck in right lane seen ahead. That's my opinion.
See this scenario ALL THE TIME----- somebody going too fast in and out, in and out, trying to go somewhere when there's really NOWHERE to go!!!
The black sedan just got caught trying to squeeze in....very selfish, very brazen, being a jerk!!! Saw he had to get into left lane to go around the other truck in right lane ahead, and made the mistake of assuming he could squeeze in front of truck in left lane, regardless of too little space and lack of safety.
He just didn't give a damn, and obviously feels he owns the highway. These small sedans abuse the highways all day long.
The space in front of the trucker was much less than it appears!!!-----it's an illusion to think there was adequate space to pull in.
Truck had no way to adjust that fast. Trucks that size can't do that. The first sedan wedged in, and then had to slow down, now being in a tight line in left lane, making the available space even less for the second (black) sedan to join in.
IMHO, the back sedan got EXACTLY what he deserved, maybe LESS than he deserved. I trust the trucker and his decisions.......that's his life, and very few are road-rage types----just the opposite........It's difficult to speed up and slow down a big truck, and accelerating that quickly isn't even possible.......don't believe he did in this video, imho.
