IF the car knows WHERE you are going and THE ROUTE you will be taking, it seems reasonable to have the car take these current factors into consideration when estimating range. Of course this assumes every trip you make would need to start by powering up and entering the destination and route.I'm not a Tesla fanboy but I think Tesla's range is a lot more accurate especially if you enter your destination. It's calculating more than historic trends to estimate range. However I don't own one so I would be parroting other Testa reviewers. I heard they're even taking temperature, elevation, traffic, speed limit, vehicle load and probably other variables I haven't even thought about into account.
I suspect many will not do this except maybe for very long trips (vacation, etc.).
