Limits of 'machine learning'

Suppose you are driving a hybrid car with a personalised Alexa prototype and happen to witness a road accident. Will your Alexa automatically stop the car to help the victim or call an ambulance? Probably, it would act according to the algorithm programmed into it that demands the user's command. But as a fellow traveller with Alexa, what would you do? If you are an empathetic human being, you would try to administer first aid and take the victim to a nearby hospital in your car.
