That is the stupidest thing I've heard. Why would you take away something that has been there for decades. Since you're constantly speeding up and slowing down, that's more important than the auto windshield wiper feature that is only necessary when it rains. How many times do you speed up and slow down in a day, everyday? Jeez, way to go GMC, for being total idiots on this one. As you can tell, I'm upset over this one.
