And what exactly would you have done differently? At what point would you have started to ignore the GPS directions and randomly drive around in an area you know nothing about?
This isn't the same as driving off a cliff or the wrong direction on a one-way road, these people were targeted by experienced criminals. I'm not saying it's Google's fault, but maybe let's try to avoid blaming the victims of a vicious attack.
I'm not really sure what point you're trying to make, since I very clearly wrote I also don't think this was Google's fault (even if they did stop sending people through that area a mere couple of weeks after this incident).
I also don't think it's fair to blame these people for this, and so I'm trying to understand what you would've done differently in the same situation.
