Don’t fall for it! 
I will not!!!Don’t fall for it!![]()
[in old timey voice] When I was a kid and EV's were new we had to drive downhill in both directions
My guess is the 50 mph is the clue. Even on an ICE every 5 mph over some optimal speed buggers the range considerably. At 50 mph (81 kph) you will be in a sweet spot. Unless driving all the way on a motorway / expressway 10 or even 20 mph is not going to extend your ETA all that muchMost of my driving was 50 mph or less and I was not running heater or ac, but I was still impressed.
First time I went to 100% - had over 300 milesPreparing for a trip, so charged the car to 100% and now the GOM says 251 miles. WOW!!!
