I am more convinced then ever that smart summon is using Open Street Maps (OSM) for parking lot mapping. This has been posted before but I want to share my results. I had 2 local parking lots that smart summon was awful at. It made horrible routing decisions. I read online that Tesla might be using OSM so I checked my area. Sure enough, areas where it worked awesome we’re mapped and areas that failed were not. So I created an account and mapped my local parking lots. I just re-tested one area today and the routing completely changed. You can see in the pic to the left was before I updated. It routed the main service road all the way around. The last pic is the individual parking aisles I mapped myself. Second pic was the new routing today. I’ll try the other lot I mapped this weekend. You might want to try for yourself.
