> if you ever see a pedestrian in your path and you are not able to avoid them, you were driving too fast, simple as that.
That flies in the face of biology and physics.
In the scenario where someone rapidly moves into the traffic from behind a parked car or some other visual obstruction: It takes up to 500ms for a human to take note (not react, just take note) of an obstacle, add reaction time to that and you'll arrive at a mean of over 1 second[0], usually more[1], before a driver can react to a new obstacle and this is for attentive drivers under good visibility.
Your argument relies on the fact that slower speeds result in shorter braking distances but braking distances are always non-zero, therefore it stands that there is a distance at which someone could move in front of the car and get hit even if the reaction time was 0ms, instead of ~1300.
