My problem is they're charging a subscription for a one-time bit flip in software. That just feels "icky" to me. With Netflix, they arguably have higher costs associated with supporting super-HD feeds or more devices or whatever else. My use of "fast mode" in a car has no such recurring cost. I have no objection to paying for fast mode once, as I would for a V8 model over a V6 model or whatever other upgrade I might want.
