Yes, and there is the case where as a new driver, less than 17 years old, I hit a pedestrian. I was driving the 20 mph speed limit through my old hometown when suddenly, with no warning, a kid about 14 darted out from the sidewalk without looking, right into my path. It all seemed like slow-motion, as I saw his friend raise his arm and yell to him. I locked the brakes of my car so that I painted the road, stopped very quickly with my then-young reflexes, and came to a stop just as he rolled up onto the hood, then fell to the ground. He immediately got up and ran away as I yelled for him to stop, and was he OK? He shook his head yes and kept running. There was no way to avoid that, and it was so quick, probably no automated system could have detected him and stopped that car any faster than I did.
