The stuck headlight door was unfortunate and I'm sure that folks at GM must not be happy about it.
When you have a scripted event like this one was, you have to roll Jim Perkin's car when you have Leann Tweeden with a microphone and a camera stuck in Jim Perkin's face.  The cars were parked publicly inside the show, I don't think it would have worked to just leave one out of the sequence.
And for all we know, that door popped open after the car started rolling.  I don't see how it helps to get upset about it.
What about the new car, did you like it, Mark?  I think it looks great, and I'm looking forward to seeing the production version.  I will buy one just as it is, but I would LOVE it if they just flattened out the front pointiness just a little bit!
Mark, nothing personal from my side in all this,  

 on me should we ever meet!
