Well if it does happen I hope your car doesn't decide to kill you.
It has to be programed with safety in mind, so in a situation where the computer has to decide in an event of catastrophic failure to either plow into a group of blind orphans walking killing them all or skidding off the road and only killing you , the logical option is to spare the many and sacrifice the few.
The car will literally be programed to drive its owner off the cliff to save those poor blind orphans .
