I was thinking more along the lines of city/town locations, topographical features. Accurate street layouts would be nifty, but not necessary. As for getting to your friend more quickly, there are better ways to travel than walking, right? I really dig the layers of realism in DayZ. I thought this idea, while not bloody likely to happen, would be an amplifier for that realism, and be pretty sweet, to boot. I'm sorry if you disagree with that.
