Currently, Grant is a mess- lane widening, (suicide lane removal) - potholes. Speedway has been upgraded and is currently in better shape. But I know this - local knowledge, and so it is my preference - but Tesla cannot be trained to honor my local knowledge and preferences. So - I just look at the weird routing and am entertained at how odd the offered path is. But it does wound my confidence for routing on longer trips. Why go through Quartzite and not Winkelman on a supercharger route between Tucson and Las Vegas?. Its more miles, goes down roads under construction. What were they thinking? So- I have to think - adding to a good suggestion local knowledge.
