At least at my end, I'm pretty sure that part of my problem isn't that signalling is causing me to override my real desires, it's that there's something about feeling that I have to signal leads to me not wanting to cooperate, even if the action is something that I would otherwise want to do, or at least not mind all that much.

Writing this has made the issue clearer for me than it's been, but it's not completely clear-- I think there's a combination of fear and anger involved, and it's a goddam shame that my customers (a decent and friendly bunch) are activating stuff that got built up when I was a kid.
