As satellite navigation systems are becoming cheaper and therefore everyone is buying them up, it's interesting to stop and consider what this is doing to our driving experience along with the whole idea of user interaction whilst driving.
We tend to trust machines to work the way they are intended. Even more so do we trust computers! Ah yes, the summum of intelligent design, conceived to make out lives easier which is exactly what sat nav does, doesn't it?
