Do the cars have a &quot;drive forward at all costs&quot; programmed into them?<p>The very reasonable and very logical assumption for the program to make is simply stop the vehicle, or reverse course until it finds a path it can take forward again.<p>Why would a car take into account the amount of human lives? If something is going cause the car to collide with something else it will decide if it can avoid that obstacle and do so, either by swerving or stopping.
