I find the routing algorithm in the Tesla nav system suboptimal. My house is in the middle of a two mile country B road which has an A road at either end. There is also a very narrow single track road that intersects with my B road. I always try to avoid the single track road, which is neither quicker nor shorter distance to my home. Invariably, from whichever side of my B road I approach, the Tesla suggests routing me around and in via the single track lane. Often this would be a longer path (both distance and time). As soon as I turn onto the B road it corrects itself, but this insistence on going around and taking the single track road gives me no confidence in the Tesla navigation algorithm when I am driving on unfamiliar roads and at a minimum I find myself also running Apple Maps or Waze on my phone to confirm the car routing.
