Prolific shooters usually know what to expect from their camera, so there's no need to experiment with settings all of the time, and if they see a P mode choice they don't like, they can program shift or switch to A/S/M mode.
I come from an age when SLR cameras did not even have batteries, leave aside digital sensors. So probably it is hard wired into me that I need to use my eyes and brain and leave aside the cameras' when shooting.
They may not use matrix metering (I definitely don't, I use center weighted, and I'm just a hobbyist) but you also have to remember the dynamic range of a full-frame RAW file is pretty good and that you can get good shadow/highlight recovery out of most situations.
When the photographer is chimping the image post-shot, if they see that the exposure is way off, you can still program-shift the settings in P-mode or use the EV dial to make adjustments and reshoot.
I am only expecting people who actually have a DSLR with either a variable or constant speed lens but still shoot auto will come and be able to try their hands out on a same scene with similar type of lighting but different shutter speed aperture combinations and later on be motivated enough to try it out on their real camera.
