 Do you want the seat to vibrate? You know, those kind of things. But that has been adopted. But it doesn't control your car unless you want it to. That's the thing. So you've got to watch. Do you believe what you hear or do you find out yourself? But it's still not good. They have had a speed warning available on many, I wouldn't say most, but it's on a lot of cars for years. I bet your truck has one.
