Actually it's not, because it's a hypothetical question being used to illustrate an idea. Instead of looking at the idea being illustrated, you are getting tripped up on the details of the particular hypothetical, that could easily be swapped out without changing the point they serve to illustrate. In this case, the question is whether Tesla would notice or care about unusual patterns of energy use. A real answer that didn't miss the point would be along the lines of "Yes, here's a news article showing that Tesla has algorithms that check energy consumption against mileage, or against a set of expected patterns." Another real answer would be "No, they don't. Here's a comment thread where Telsa users have talked about their experience with charging stations where they didn't run into such limitations." A point-missing answer would be "hey, bitcoin mining isn't that profitable!"
