The Bullitt Car Chase

I mentioned Bullitt the other day, and how I hadn't seen it before. Sure, I had heard about the iconic car chase sequence in it, which is one of the things I was looking forward to. It surprised me a bit: the entire scene had no music in it! That, and it had almost no dialogue either; it's just the sound of gears being shifted and tires squealing. But it's the lack of music that I found more interesting, since most of the chase sequences that have come since then (and a lot of them beforehand) have uptempo music accompanying them, as if to try to reinforce the fact that the viewers should be getting a rush of adrenalin.
