I don't think that's generally true, or at least, the contrary notion is also true some times. I'm pretty sure that if someone asked me the product of 13 x 6, they would trust me more if I punched some numbers in to a calculator and gave them a result versus if I just did it in my head. I don't know, but I think the likelyhood of me mistyping numbers is embarrasingly high, and probably about as likely as a mistake in easy mental math.
It's also closely linked to your third point though. Liability with self-driving cars is difficult. When people talk about self-driving cars, they sort of just hand-wave away the fact that there will be accidents, so as to avoid this difficult problem. This does not instill confidence.
