When headed somewhere on a highway trip, say to a lake, the nav system should notify when the car is approaching The Point of No Return, the distance and energy to get back to where I came from.
If you typed in your destination it should be a simple add-on to the computer. It knows how much energy you’ve got left and should let me know that my destination requires a place to recharge, or other actions may be necessary, such as returning home.
A mix of navigation location status with energy usage, something only Tesla can provide. Does not seem like a difficult task, but not trivial either.
Implemented with 6.2 software.
