Driver explains brake check caught on dash cam

This dash cam video was posted to YouTube Christmas Eve, Dec 24, 2016. We’re going to let the person posting it explain things: “This is from my personal dash cam. I passed another truck that was going approx(imately) 5 mph slower than me, who decided to speed up when I was almost past him (no sense in slowing to get behind him, I’m literally past his cab). Not my fault it took me a single minute (literally, only a minute) to pass him. This car apparently thinks its my fault, and no, I didn’t cut him off, he was a ways back when I got over to pass. This was in Cedar Rapids, Iowa. Westbound Highway 30 between the exits for Edgewood Road and Williams Boulevard.”
