Looking at the methodology here, I don't think this test is likely to be representative. There are two important differences between a test dummy and a pedestrian. First: pedestrians glow in infrared; and second, pedestrians move, even if it's only shifting in place. Both of these features of pedestrians are extremely useful for a sensor that needs to find them, so I expect using a still, cold dummy to make them perform worse than they would in the real world.
