Well, there's certainly not a 100% correlation between camera preferences and transmission choice. I drive a manual transmission, always have, always will. I won't settle for anything else, and am perpetually annoyed and bored by automatic transmissions.
However, I don't really enjoy using manual focus on my camera. It takes too long, I have poor luck with precision, and it seems an unnecessary burden for no clear physical benefit. With a car, there are obvious benefits: a manual generally gives improved power transmission and greater fuel economy, and driver input into the choice of gear can keep the car in the right spot on the tach for upcoming conditions. An automatic transmission cannot anticipate, therefore it's at a disadvantage. I fail to see the disadvantage inherent in AF. It's quicker than I am, more accurate than I am with my matte screen, and there's no difficulty in changing the subject of interest so it will focus on what you want. The only time I routinely use manual focus is shooting macro, because I use a macro focusing teleconverter. If I was willing to pay for an AF macro lens, I'd have that too.
Manual exposure is similar in my mind. I use it with off-camera flash because Av mode isn't smart enough to do the right thing with my wireless flash transmitter (wants to expose for ambient). In regular shooting though, I don't see the benefit for me. In manual, I'm just going to adjust based on the exposure meter in the camera anyway, so why not let the camera do it. I mostly only care about aperture anyway. It makes little sense to me to use M mode outside those rare instances I deliberately want to use "improper" exposure.
I respect, and to some degree admire, people who enjoy using MF lenses on their cameras. But believe me, it's not borne of the same mentality that makes pepole drive stick. It doesn't have the same motivations rooted in sheer practicality. The obvious benefit in MF just isn't there for me.
