I disagree with you Alex. Using your reasoning, cars should be designed to save lives in every accident, yet look how many people die each year from taht cause. Here in the US, about 4-5 people die each year from ride caused injuries, out of several billion rides taken in amusement parks and carnivals. More peole die from falling in their bathtubs! Why don't bathtubs save every life? If you don't feel safe on rides, nobody is forcing you to go. Sit on the bench and wait.
