Let me control the zoom. Sometimes I want to see my whole route. Sometimes I want to see city streets. Sometimes I want to see as far as the next big city. Only I know which of these I want to do. But you know what I never want to see? A beige screen with a blue line across it representing the 50 feet either side of my car. That, however, is what every modern satnav insists that I see for the entirety of my trip. If I dare zoom out, it'll either zoom me right back in after five seconds, or stop tracking along with me so that the little car icon drives off the side of the map and I see a little "recenter" button that will zoom me back into that "1m = 1m" view that it loves so much. It's maddening.
