When one wants to enter a ride one would think that the operator has been vetted for safety which in turn means they are the "responsible party" who keep the maintenance and upgrades as required by the governing laws. If one wants to shirk the "responsibilities" then one should be held responsible by those who enter the ride and those who police the ride. This being the case then operator is going to have to explain why he was not a responsible ride owner which in turn put the safety of riders in jeopardy
