rockies or smokey's

I like cruise and use it a lot. But, it is a dumb robot and it cannot think ahead. On secondary roads, that are twisty turny, that I have driven for years, I know what is coming next. Why let cruise top a mountain at 55, just so I can stand on the brakes for the 25 mph turn on the far side? Those big, long multi mile grades out west, cruise is great. Appropriate Technology for the task at hand. Now, if cruise could be slaved to GPS, and interpolate elevation change, and the customer could do a little programing, yes, then we could almost use it all the time. Might as well get self driving too!!!
