Well, it's not splitting hairs,it's just Murphy's Law: "if it can break, it will"; so, in the OP's case it was the battery, but next time it could be a computer glitch, a bad sensor, a bad BCM, etc. I fix man-made machines with electronic "brains" for a living, and I've watch brand new machines fail right out of the box. We're human and what we make isn't perfect so I am merely eliminating one more possible source of error/failure, that's all. And it's not that "I don't like/care about saving the planet, etc", because I do...I just go about it differently, like planning my route: avoid frequent stops/red lights, or finding the most direct route from point A-B...stuff like that. If traffic lights=bad fuel economy, then drive an alternate route. Sometimes lo tech is just as good or even better than hightech gizmosAnd if the two were related, which I doubt they were, then 1 data point does not indicate a trend. Especially in a pool of 120,000 or so. There will always be outliers who have crazy things happen. That's just statistics.
Again, I don't care if anyone uses it or not. I just want everyone to understand why. I hate people making decisions based on bad data, or even no data. Learn everything you can, then decide. Even if your reason is "I don't like it", that's fine, as long as you've tried it and/or given it a fair shot.
