One driver is lucky to be alive after his car was stuck under a truck on a California highway Wednesday. The scene was filmed on the 15 Freeway in Los Angeles County and posted to Facebook by another motorist, Brian Steimke. In the video, the big rig is caught dragging a Nissan Maxima for half a mile. The tires were blown out of the Maxima and the driver is seen waving his hands, begging for help. The driver said he "didn't know" he had a car stuck under his truck.
