Obviously it's a button that turns off cruise control. I believe it also removes any set cruise so you can't just resume where you let off. Basically it's the button that I use the least when I drive my dad's truck seeing as you can just tap the break to turn off cruise.
...Or you could be trying to make a joke, but whatever.
This is the most idiotic post that I have ever seen. Clearly, this topic is not a joke? What is wrong with you? Is your brain that small that you would think a joke like this would be funny? What kind of human being would think this is funny, because I literally stuff my self from how loving stupid this kind of comment on a question like this was.
How dare you loving post some non sense stuff like "It's for cruise control". I hope you're banned for this.
push it and a hookshot will shoot out of the glove compartment
Why can't you post a real answer that makes sense, like what this smart man has done? You've been reported, may god have mercy on your soul.
this is joke
