Another zombie story
Why does this story keep getting republished every few months? I'm not sure if it's fearmongering or stupidity by the authors. The fact is that HUMAN DRIVERS don't make decisions like this. There are no split-second thoughts of "who should I kill."
As for automated vehicles, since they will drive more cautiously by default, and they will constantly be aware of their surroundings, it is extremely unlikely that this type of logic needs to be built in. They'll just stop, because they will have time to stop, because they are constantly aware of their surroundings AND they will be driving at safe distances allowed for stopping.
