Select models of Honda vehicle have a Lane Assist System available (marked LKAS on the menu) that enables people to be safer as they travel in their own lane. That's sort of what driving is all about, at least in a safety sense. It's your goal to stay in your own lane and never veer over to the left or right enough to cause an accident. Changing lanes can sometimes be dangerous, especially if it's on a heavily traveled highway area where many cars are lined up making their journey. The purpose of Honda's Lane Assist feature is to give you an alert when you begin getting out of your own lane and become dangerously close to crowding someone else on the road.
