Autofil Magazine sets out to test the range of the Tesla Model S in cold conditions with a cargo area full of Ikea furniture, skis, a mountain bike and have some lead footed fun along the way. Before starting out, on the 270km journey the driver places a piece of tape over the range display in the car so he won't have any anxiety about how much remains. The Tesla is rated for a range of 400km, but he thinks 300km might be more accurate given the conditions. This limitation doesn't worry him though and he has no need to be constantly checking the range remaining. Someone is following him, he needs to make a point about the range for the review, if he gets stranded all is not lost and so there is no need to worry.
What do we worry about that we can't control? What limits should we acknowledge and then put a piece of tape over to ignore?
