I use Waze for Voice, and Tesla SatNav for map (voice on mute). Yesterday it took me off dual carriageway just before an accident. I was in two minds ... traffic not slowing, Tesla traffic not showing anything, but as we came up off the slip road we could see the brake lights and stationary traffic in the distance.
However, it seems to me that the voice on Waze has changed recently and the one I am using has been watching Bjorn ... most times, but now always, it says "Take the Nth Exieeet"
