Relatively speaking, he was a continent away from the GT! He got real close to the cement benches in the semi circle though. Some of the places were clearly rehearsed (e.g., the truck on two wheels and others with tire tracks visible) but some, especially some of the brick courtyards, were not (or they had cleaned them in between takes)
I love to watch him drive. But I liked the San Francisco one with the retracing of the Bullitt sequences (and the appearance of a Bug) better.
