I have a Mid Range Model 3, so it works out to 1% = 2 miles for me. But on this last road trip, I had the range estimate give me some wild predictions like 25% of the battery to go 100 miles. If I had followed the car’s directions, there were two times I would have run out of charge miles from a charger.

After reading the details of the “range projection algorithm” it 100% explains the weird projections I was receiving.
