The nav is only the most basic and needs lots of work. No manual reroute or alternative routes, like my 8 YO Acura. They need work here. Traffic seems to work well and while it will now recommend an alternate route, based on heavy traffic, it will not show the alternates so we can make a decision on which to use.
Tesla really needs to partner with the many nav and mapping companies that do such a better job. I am actually surprised, with their partnership with Garmin, that the nav is so unsophisticated.
