A few years back I was the passenger in a car waiting at the light in the right turn lane at a ramp to get on the expressway. In the lane to the left was a semi truck. When the light changed, the truck proceeded to take the right turn, and as he did, the rear wheels of the trailer ran over the front of the car I was in. There was this terrifying moment when we realized that the truck was going to hit us and there was nothing we could do. In my opinion there was no way the driver didn't know what just happened; he just kept going though. I jumped out of the car and chased the truck down the ramp a bit trying to get his attention and/or a license plate.
