Re: Multi level towns
When I've used satnavs round cities (various of each) I've noticed that even though they calculate the times for walking the routes often seem to follow busy car routes. So it'll route me to, then along a busy main road, when I was already on a quiet parallel road that goes to the destination. In many ways the same way as it would take me on a circuitous route to the nearest main road when there's a more direct route closer to where I am , when I'm driving.
