The standard maps are fine and navigation does re-route based on live traffic even if the map doesn't show the traffic visualization. I have my work and home addresses entered so each day as I leave my house I touch the Navigation button and drag down. This routes me to Work automatically. I do the same as I leave work (or from anywhere not Home) and it routes me Home. I always look forward to finding out which way it will take me home that day.
Also, to see available Superchargers even when not planning a trip - you can click on the lower right of the screen. That will reveal a lightning bolt icon. Click that icon and it will display all the SCs on your screen map.
Another feature I use from time to time is sharing with my car a destination found on my phone using Google Maps. Just find it and Share and then select the Tesla App. I'll do this sometimes before leaving work. Then when I get in my car, the destination is already programmed.
