Does anyone know if it will now actually update the route if traffic conditions change? It may pick the best route when you start, but for a multi-hour drive traffic conditions change and you may need to reroute. I've taken to regularly looking at the reroute option just to see if another route now has shorter time, but it really should do this automatically.
