text: Technology fails everyday so why put it in a car and put human lives at risk? Using the heads-up system is a good idea however it could also fail resulting in the faitality of another human. Using the heads-up system could get the attention of the driver to let them know that they need to take over. What happens when the driver doesnt take over and the car continues to have a mind of it's own. Again possiable resulting in an accident and a possiable faitality.
