My top car chases would go to the one toward the end of Ronin (theres like 15 car chases in that flick)
matrix 2 had a sweet one
Bad boys 2 when they beat the crap out of that Ferrari
Dukes of hazard when he's drifting the shit outta that 'round a bout'
I've also heard that the car chase in the original 'Italian Job' was done without police knowledge and some scenes were real cop cars?
I love car chases
