So I think I had emergency braking kick in today. I was rubber necking and didn't notice traffic stopping in front of me. I hit the brakes hard and then heard a beeping. When the beeping happened I think the brake went in further than I could push it and the car stopped shockingly quick. Is this normal? In other words can the vehicle brake harder on its own than I can? I actually ended up stopping so quickly I had to accelerate a bit to avoid being rear ended. Very impressive for a 5000lb car.
