I sometimes wonder if Tesla should be getting into autonomous nav with some of the evident problems they have with high school geometry and recharge planning.

I sometimes wonder if Tesla should be getting into autonomous nav with some of the evident problems they have with high school geometry and recharge planning. That said, the author of the article used SG&A expenses as a club to smack them with, without bothering to examine the reeds that make up the club. Tesla has more in common with Amazon than GM for a business model, they've got a voracious R&D appetite, and so on. They may well fail, but this article doesn't even seem to have a grasp on what they are, hence the measurements are all of time in furlongs per fortnight :-)
