Driver gets cut off and his car nearly tips over

I'm always afraid of getting cut off at the last minute by lane-changers who aren't paying attention. It's happened to me more than once when I'm in the car pool lane and some idiot stuck in a traffic jam decides to change lanes without looking, forcing me to slam on the brakes. Here's a guy who got cut off so harshly his car rolled on two wheels for a second. Glad he caught it on his dashcam.
