#2 she couldnt look underneath the car, she was on her knees, and the only time she looked up was 2 seconds after it passed her...

i dont see why we have to be so surprised about animal intelligence, just because theyre not a humanoid doesnt mean they arent capable of knowing how to eat a nut, crows drop nuts from traffic lights for the cars to run them over, spiders make webs to catch prey, its all the same, just because this monkey decided to use a rock and a flat surface above the ground doesnt mean we should think monkies are all the sudden intelligent.

#4 They were going fast because they're car was gaining speed from the conditions and the slope of the hill, even if they hit the brakes it wouldnt have helped, probably would have hit more people. unfortunately they should have known how to deal with that kind of situation though.
