Teething trouble with safety systems ?
I agree with Colm - safety equipment should not have teething troubles.
Taking the attitude that "ah, sure, it's grand because the other safety mechanisms will kick in" is all well and good until the other safety mechanisms also fail.
I am no engineer, but I would have thought that signalling systems were reasonably straight forward to program - there are only so many possible
states/paths that can exist and need to be catered for.
