Three part question: 1) Am I missing it somewhere? Can the cruise control not automatically adjust when a new speed zone is identified? The manual seems to indicate "no", but there's been several points I've found where the manual doesn't meet with reality so I figured I'd ask. 2) Assuming "no" above, is there a reason *not* to develop such a feature? Safety, etc... something I'm not thinking about. I'm pretty sure I can implement a method for auto adjusting, but just because I can... doesn't mean I "should". I don't understand why they wouldn't, but likely there's a reason I'm not immediately recognizing. 3) Any interest if I can/should/do? It shouldn't be to hard or expensive to accomplish, and I think I can do it entirely passively. Of course I need to bust out my analyzer before I know for sure but wanted some initial feedback first.
