My reply is anti-everything that has been mentioned here, except the statement about AE not being necessary, which it is indeed not.
What matters for street photography is fast action and sharp focus. Unless you are intentionally isolating something/someone, zone focus with an understanding of your DOF for any given aperture is more important that the camera. Having a good understanding of the light conditions where you are is important. Being able to judge changing light conditions and opening up / closing down aperture as needed by eye with occasional reference to a light meter is important. AE can be fooled - cities with deep canyon walls are high-contrast scenes and their judgement in such situations can be wrong - best to be depend on one's own common sense in these situations. Being able to reload quickly is important. And finally, some level of unobtrusiveness is important - quiet, non-shiny, small, etc.
In other words, certain skills are more important than the camera per se in these conditions. Judge distance, light conditions, and framing by eye. Have the camera preset for the majority of these situations, know your camera well enough to change the settings quickly when called for, with a minimum amount of fumbling. Be able to reload with one eye on your surroundings.
Given that, my choice is usually a camera that offers manual aperture/speed controls (AE optional, but I don't factor it into my decision as long as I can turn it off), good viewfinder, good distance markings on lens barrel (easy to see/read), easy handling, easy loading.
In reality, I often reach for either my Bessa R and a 35mm lens (although I am usually a 50mm guy) or my Olympus XA or XA2 (zone focus, not an RF). But that's just my choice, and might not be best for others. I'd love a Contax G2, as long as I could turn off the AF/AE and easily set the aperture/speed controls for these situations.
