When navigating to a location, offer three or four choices, perhaps as fastest, shortest, cheapest (i.e. no toll roads). Each route would show the number of miles, estimated time, and the actual route on the map with different colors to identify each route. If no selection is made within say 10 seconds, default to the fastest choice.
A choice based on the shortest time based on current traffic would be fantastic, although we are unaware of any current car navigation system that has this feature. Another routing consideration should be where superchargers are located (for longer routes). In this example, Quick2 may be the only route that truly works, with a stop at the Harris Ranch supercharger.
Some more advanced navigation systems offer this or close to this level of functionality.
Tesla now provides traffic-aware routing to identify the shortest time, but only the one offered routing is provided.
