On the high wind point, with how much the robot weighs it's a bit unbelievable how it could tip over at all even while in motion. If winds were that strong, none of those girls would still be standing much less Koujirou. It's not like the robot tipped forward while in motion, it tipped over sideways. If it was a freak accident of the wind it's a bit unbelievable. But if it was some outside source making the robot fall over it would be more believable.
