It doesn't sample the condition of the oil, true. But it's a lot more sophisticated than just miles and time. It understands whether your miles are short trips with lots of cold starts (shortens the interval) vs long highway trips; whether you're thrashing on it (shortens the interval) vs driving like a grandma; oil temps; and probably some other things I'm not thinking of. It probably does a good job of figuring out when you should do your next oil change.
