And a vehicle not to be used in any chase scenes....
The NASA Crawler-Transporter (used to move the Space Shuttles to their launch sites) may also fall in that category.
Another view that shows the scale so much better (note the miniature people by the tracks)
There's a NASA video I saw a while back that shows this thing in action and it was featured in an episode of Dirty Jobs recently. Beware, this thing can really book with a top speed of 1km/h (the crawler, not the shuttle).
