All, I keep reading posts where people are requesting turn-by-turn navigation - I still fail to understand why this remains to be such a prevalent request. Hopefully this thread will answer some questions. I've been using the iPhone GPS a lot in the last 3 months since I got it. The way I do this is I do a directions search so it shows me the blue line, i then tap on the button to track my location which zooms in to my current location and tracks where i'm going. (note that I don't press on the "Start" button since this would give me the useless next-previous buttons to tap through my journey) The iPhone is mounted in my dashboard so that every time i look down to check my speed i can see immediately where I am or if any turns are coming up. I find that this works incredibly well for me and I don't see how it would be any less safe than looking at a turn-by-turn GPS mounted to my windscreen. On the other hand, I find that turn-by-turn GPS systems can sometimes lead to quite dangerous situations. People depend on the given directions so much that they lose their common sense. Example: "Turn left at the next crossing." Issue was, there was a new round-about at the next crossing so by turning left "hey, thats what my GPS showed me!" the guy actually tried to go the wrong way around the round-about!!! Yes, roads change! But general directions don't. So by just seeing in which direction I need to go (ie. next crossing i need to head leftish) i know where i need to go but i'm still having to think, which i believe is quite an important thing to do when driving... So in all honesty, why do we really need turn-by-turn GPS?!
