What's the greatest car chase in movie history?

I'm sure everybody has pondered this question at some point in their lives. Fortunately Les Jones has assembled all of the relevant clips and is running a poll here. Go and vote - you know it makes sense. For what it's worth my money is on the chase from Bullitt - superb driving, Fastback muscle cars, Steve McQueen in one of his best roles and it reminded me of just how good the San Fiero bits of GTA:San Andreas were.
