Yep, yep-so, as a scientist, I am aware of the science.
Just like the soon-to-be-mandated auto-stop/start feature, I do not have to like the always-on A/C defrost. It makes absolutely no sense in the winter when the heater works just as well or better. The air is already super dry (where I live in the SW). The option should be there to turn it off when deemed unnecessary. I have found that the A/C defrost helps during the warm, wet seasons.
The issue is deeper than that, and is part of an overall bigger picture now. Mine is a MT; when the A/C kicks on (unless I am really moving along), much of the time it coincides with shifting. For a while, after I purchased the Crosstrek, I found myself stalling at lights/stop signs because of it. It was not an issue with it being a MT, because I have owned and driven many different types of MTs. So, I guess I should have said that if I had known about the low-powered (low-inertia, really) engine being overcome by the A/C kicking on, that would have been the dealbreaker.
