There's miles of difference between the brakes not engaging and not showing significant signs of slowing down. It's enormously unlikely that the Uber car failed this badly. The most plausible scenario is that the car did brake but just didn't leave skid marks. The car not recognizing a human in its path would be a shocking failure.
