For his first recharge, he charged the car to 90%. During the second Supercharge, despite almost running out of energy on the prior leg, he deliberately stopped charging at 72%. On the third leg, where he claimed the car ran out of energy, he stopped charging at 28%. Despite narrowly making each leg, he charged less and less each time. Why would anyone do that? Time constraints? Maybe he had a meeting to get to (simulated)? Arguably, people who can afford to drive around in a $100K electric car probably set the meeting starts by their arrival.
