I guess that's why the manual says not to use cruise control in heavy traffic..which I don't. Therefore, as far as I'm concerned, there is no problem with my usage of cruise control.
I don't care what the manual says Brian. If CC is used at high speed on the open highway, your reaction/response time is extended and even more time critical, taking you a longer distance to react. Period, no debate.
Fine. I'm going to come right out and state that I don't think it matters in the situations where I use it. Reaction time isn't that important on a limited access highway with light traffic.
