Ronster - I just happened to be at the dealer today, as one brake light burned out when I was literally a block away. I stopped in and talked to the service guys.
They told me that the tip DOES learn in the "D" mode. They said the longer I drive it in "D", the better it will be for my driving style. So.... I am going to spend a couple of my commuting days running it in the "D" mode and seeing how smart it is.
I have very little faith, but I'm a cynical guy.
I did lose a little respect for the service guy because he didn't know about the requirement to hit a certain RPM for the sport mode to stick.
I think I'm one of the few people who read manuals cover-to cover.
Thanks for the comments. It's nice to have one person listen to my whining.
