Does it come on automatically when you start the truck or is it a Manuel option.
If you start off tracking into another lane how violently does it correct you, how does it know if you want to merge into another lane, is that by turn signal prompt.
Is there an acoustic signal that alerts you additionally, that might drive me crazy, I have one in the semi truck I drive at work if we start to off track slightly which I understand but in my personal truck I would get sick of it. Thanks for the comments, I like the idea of an insurance discount, never thought of that.
