In the UK we had the very rare incident of a digital TV box going crazy and sending an em signal that got picked up by the EPIRB marine beacon satellite system, automatically summoning the Coastguard to an old lady's front room. Technically she was legally at fault as she was responsible for the maintenance of her 'kit' but clearly she was not held to be. Million to one chance. Thing is, it happened again with a totally different box a few months later. The odds were staggering, but none of us in the UK could be bothered to calculate them.
So, if your phone automatically summons the fire brigade before it burns you, would that be considered a 'feature'?
