I'm not, but talk about a gold mine of testimonials right there. Edit some of the segments together and come up with a compelling commercial, or three...

- could not get car to skid (Q7)
- needed to get electric motors onto the wheels to get them to spin while car is in the air and CGI some of the effects as it gets set down and speeds away (Q7)
- couldn't pry roof metal apart with hydraulics (R8)
- couldn't get R8 to flip over

As Jon Favreau said, they kept fighting the Audi engineers to make the cars do what they had storyboarded: "Bad for making movies, great for driving!"

Just watched the movie, the clip about the R8 seems to be very scripted by Audi.

So there you have it. If you get into an R8 and happen to find yourself hitting a ramp and into a post, you're just gonna spin around and skid out and not flip, roll over, etc.!
