You missed my point, which is that it's easy to achieve rated range in a Tesla with real-world driving.
I have not taken care at all to drive my Model S in an efficient manner, and I still have an average of 315Wh/mile over about 8,000 miles of driving so far, where 300Wh/mile is rated efficiency.
The bit if data you are leaving out is the nature of the terrain and traffic you experience. I am not disputing your numbers at all, I am simply saying more data is needed in order to fully evaluate it.
Beyond that, the truth is you cannot get the rated range because that would mean draining the batteries to zero. Real range anxiety, depending on where you drive, starts to come in somewhere below 50 miles from fully drained.
You also have a difference in performance between summer and winter driving. If you have a short daily commute, the combination of the "off" state drain on the battery overnight and the car warming or cooling the battery pack while parked in cold or hot weather can have an impact on available range and performance.
BTW, I am NOT saying any of this is bad. I am simply saying these are realities of the contrast between advertised specifications and performance under real life conditions.
That's fair. I think we can say there are two kinds of "do you achieve these numbers in the real world?" One being whether you can do so without completely artificial conditions, and one being whether you always get the given numbers. It seems we're just talking about different ones there.
