On 1/7/05 I walked by the L.M.A. set and heard cars so I walked around the outside and saw some of the stunt drivers training (grr, no camera). If you take the Backlot Tour the tram takes you past the set and, if you time it right, you might see them practicing. Also, if you hang around where the tram unloads you can, depending on the sequence, see a few cars chase each other. No word on preview dates yet.
