This seems like it should be pretty straightforward, but I can't decide how the navigation system choose which route to display.
In my old Honda, the nav could route by a direct route, easy route, or fastest route. It didn't consider traffic. The Tesla nav has the option to consider traffic, and use that to decide which route would be fastest, but doesn't necessarily suggest the fastest route for me to follow, nor does it chose the shortest route, nor does it choose the route I would consider to be easiest. I do have the option to reroute for a faster trip selected, and have the threshold at about 5 minutes.
Example - Leaving my house to go to a particular destination, I'll use the nav because of potential traffic issues on one of the three most common ways I take. Each route is similar in total distance, though one route involves more up and downhill travel than the others. The nav will often suggest my least favored route first and give me a time estimate -- say 25 minutes and arriving by 4:30pm. That indicates to me that I'm unlikely to have traffic issues as the "preferred" route seems to be the one that travels through the area most likely to have slowing if it exists.
If I choose a different route and start driving that direction, the nav will adjust and reroute. It might now display that the trip will take 29 minutes arriving by 4:34pm. I'll ignore the reroute and continue for another minute and the nav will adjust again, now displaying a route that will take 19 minutes arriving by 4:25pm. Half way through that route, I'll ignore a suggested turn and find the nav updates from 10 minutes remaining arriving by 4:25 to 7 minutes remaining and arriving by 4:22. The original route would have been slower by more than the threshold that should have triggered a reroute when the whole trip started.
Does anyone know what criteria are actually being used? Things seems to be much worse since the latest updates. A couple of weeks ago I was provided with a route that was estimated to take 3.5 hours for a trip that Waze estimated at 90 minutes. The Waze route took main streets and major highways along a fairly direct route, so I have no idea what the Tesla nav was thinking when it came up with a 3.5 hour route.
