@Stavinski , it would have been interesting to use the Tesla NOA (Navigate on Autopilot) to show the estimated consumption to your destination.
And also displaying the consumption graph, as the car constantly recalculate the available range based on your current driving to give a better prediction.
The NOA feature doesn't (yet... ) supports
Waypoints like when using Google Map or
ABRP (A Better Route Planner),
so you would not be able to determine directly if you would be able to return home without stopping at a super charger.
Note:
I prefer Tesla displaying the "SOC %" (State of Charge Percentage) instead of the "available range" which is more intuitive.
This is like when using a phone, and having the choice to have a phone displaying "2 Hours of use available" instead "10 % battery available."
So considering the Model Y LR AWD 326 miles (EPA) range estimate, between 80% and 20% you would have in fact about 195 miles usable range.
And the original "71 miles" of range available would have shown about "22 %" of battery available, which would have raised concerned before leaving home.
After driving 24 miles, the range should have been around 14%, and after return home for another 24 miles, you would had about 7%.
In your situation, after driving one mile instead of 64 miles range, you would had seen about 20% and instead of 22 miles it would have been 7%,
and then instead of 7 miles it would have been about 2%.
