The point behind it is thus... We didn't hit a person because (although it looks fast on my crappy camera with limited frame rate) as we approached the zebra we were going at a speed that allowed us to stop before our wheels even touched the zebra. If we couldn't have stopped before crossing the crossing, then it would have been dangerous driving. It's why I had to provide a freeze frame, because the child is spotted and the vehicle brought to a halt within such a short period of time. The dog running was travelling faster than a human, and yet we still stopped in time. So my point is - even though it looks like we are going fast, we drive so that we can stop given the hazards of the road - those hazards include kids on scooters (and their dogs) dashing out in front of us despite the lights and sirens.
