I just can't comprehend how people can accept that. I mean sure you can use your handheld computer, but when I wouldn't know where I am and what I need to do to go to where I intend to be, I would feel very alone, lost and abandoned, like being Napoleon on Elba. In a completely foreign city, often I just look at a map before the journey for the general direction and then just keep running, without thinking much. That works quite well, because street design is actually logical and where it isn't there are signs. I'm surprised that you often wouldn't even need a map; because you just need to look at the signs, they will tell you.
