I was wondering very much the same sort of thing earlier today, though I
grant I was musing more on cellphones and other weaker QRM.
A friend who was involved in automotive microcode for a US carmaker,
rather a while back, told me he had found some hundreds of disaster-
guaranteed code flaws, ranging from software race conditions resulting
in indeterminate results (roll dice) to brakes, steering, or other major
subsystems failing hard.
I doubt things have got a whole lot better. I am very decidedly troubled
by this bit of testimony. These are man-rated systems chock full of
electronics, and EMC testing damn well ought to be mandatory.
