Seems like it might be an unnecessary option for this particular car.
We're going to start by apologizing for the camerawork in the following video. We didn't shoot it, and it looks like whoever did has no idea how cameras work. But that's okay, because what's really important is the audio anyway. What apparently happens here is that the 1,500-horsepower Chevy Camaro built by Henderson Performance was doing a pass at the Texas mile when it blew a head gasket and the OnStar system automatically called a representative.
Why it never occurred to anyone to disable this feature isn't clear, but hopefully they'll think to do it now.
