In no particular order (except the last one, which is, IMO, the greatest of them all)
The Rock - Hummvee crunches a Bug, trolley smashes a yellow Ferrari, great stuff
Ronin - tunnels, against traffic, Robert DeNiro.. very cool
Bourne Identity - The Mini in action (don't know how Italian Job compares, haven't seen it)
French Connection - one of the all-time greats, set a standard
Die Another Day - Bond car vs. imitation Bond car. Excellent 007 action.
And the greatest of all time. This car chase defined what a car chase should be. Run at full speed (no speed up of the film a la Gone in 60 seconds) and driven by the actors. Every car chase (and those taking place in San Francisco in particular) were based upon this one. The cars involved: 68 Fastback Mustang and 68 Dodge Charger. The over the top cool factor: Steve McQueen. The movie: Bullit
