On a two lane road I us a lot the posted speed limit is 55 mph however when I turn onto the road going north the speed limit is displayed as 45 mph. I understand that Tesla uses Google maps and so I signed into google maps and changed the speed limit to 55 mph and got a conformation that the edit was approved. The next time I drove on this road as I made the turn there was a 55 mph sign on the display however as I finished the turn and aligned with the road it was showing 45 mph again. What is puzzling is that when traveling south bound on the same road the speed limit displayed is correct (55 mph). Anyone else have a similar problem or a solution?
