A YouTube vlogger was airlifted to a California hospital with "moderate to major" injuries after livestreaming the moment he ran a stop sign and drove into the path of an oncoming semi-truck in what police are calling "a case in point for the dangers of distracted driving," KTLA reports.

Actor David Slavitt began broadcasting to the 1,500 followers of his LameDuckG YouTube channel last Thursday as he drove his Honda Fit through the desert in Llano, California on his way back from doing camera tests for what he called a "Harry-Potter-knockoff kind of movie." Throughout much of the original 45-minute video (we've added a clipped version below) he rambles on a variety of inane subjects while the phone rests on the dashboard.

But halfway through, he switches to driving with one hand and holding the phone in the other. "It's a little bit more fun, doing driving streams," he says. He eventually ends up on a dirt road and complains about the rough ride in between detailing his plans for lunch. His pontifications are interrupted a few minutes later when he comes to an intersection with a paved highway, tells everyone how glad he is to be off the dirt, and quickly turns onto it without stopping.

You know what happens next, but if not, his terrified scream says it all. And yes, that is the red big rig you see reflected in his sunglasses a moment before impact.
