I can't count the number of commercials I've seen for Fords and Nissans and Subarus and every kind of modern car that has this exact feature, and this is exactly how the advertising plays out. Someone sprints in front of the car, the car stops automatically, everyone is safe, pedestrian continues with their life. I've never used it in real life, but I assume it works how the ads show it.
If Uber can't match a $25,000 off-the-shelf floor model mass-market midsized sedan for collision avoidance, it's hardly a self-driving car.
The system in my car does this but only under a certain speed, much lower than what the vehicle in this video appears to be doing. It's intended for stop-and-go city driving or to avoid hitting a kid that sprints out of a driveway in a slow residential area, not to slam on the brakes to avoid hitting a deer or person at 40mph.
