Digital control allows for digital override. In the not so far off future, automatic driving systems are going to radically reduce the number of car accidents, and for every 1 accident that occurs because of a firmware bug, 10 will be avoided because computers will be that much safer drivers than humans (who should never, ever be driving in the first place - they kill about 40,000 people a year in the united states, and maim hundreds of thousands more. )
