The journalist that did the "original" review was not able to charge his car to 100% I bet that when he charges everything else he understands how it works. It's just not good enough to write a review based on wrong assumptions, especially if you already have a history of not "liking" ev's.
Imagine getting up in the morning, you check your phone, 25% ohh well i am not going to talk a lot to day so says my crystal ball. How many would do that? The NY journalist did his first drive in the Tesla S, and decided to base his drive on his experience, which was zero. Normal people, and other reviewers knew better, better charge to the max when i am actually testing the limits of the car. Not the limits of the reviewers knowledge.
If he had done as he should he would still have been able to write all the negative parts, the drop over night the limits because of the cold etc. it might have been a worthwhile article, like this one.
