I was driving down a residential street at approximately 20 miles per hour. The emergency braking system suddenly activated and the car slammed on the brakes. There was nothing in the road at all. Some people were on the side of the road and they confirmed that there was absolutely nothing in front of the car to cause the braking. The brakes engaged so rapidly that I have whiplash in my neck. This was a very scary incident and felt very unsafe. Had there been a car behind me, they would have rear ended me for sure. I feel traumatized by this event and am now scared to drive. The emergency braking warning came on at the same time the brakes slammed.
