You are correct that I did blame the cast member directly in my first post and I still think that is a valid scenario. And others scenarios are just as valid as well (even yours!). One example of a valid scenario that was brought to my attention by another OP...riders trying to slow themselves down could also add to the jam up. It could have been a number of things including a cast member not paying attention!! Disney cast members are humans and not perfect. Everyone can make a mistake. Including cast members, my family, and other riders.
Here was my reason again for putting the blame on the cast member...there are 3 slides and I sat at the bottom pool for a good 45 minutes watching it. The space between riders was really off on this one slide. I was not the only family with an issue. One woman was freaking out because there are was big wait for her second daughter to come down. I also saw a brother and sister come close to crashing and then there was of course my family's little accident. Look, I see your point about the red/green light. I did not know about that because I was not at the top of the slide. But I think that as cast member they hold some responsibilty to control the flow of riders. They shouldn't just be standing around not paying any attention.
And once again it is possible that my family did not pay close attention to the lights and add to that people slowing themselves up. I SEE YOUR POINTS! But add to that a cast member as part of the mix.
I only posted this to tell other families to be careful. That's all
The problem with your point is that it is impossible for a cast member to control when the rider goes on the Storm Slides. Reason being is that it is entirely up to the rider when he/she goes. You are basically sitting at the top of the slide, and push yourself off when the light goes green. How can the Cast Member control this? Would you expect them to physically restrain the guest to prevent them from going?
The Storm Slides are basically operated by relying on two things.
1. The automated traffic lights detect when a rider is a safe distance from the top, and signal green to let the next rider go.
2. The riders must obey the traffic lights and only go when green. They also need to follow directions to lay back, feet crossed, and cross arms on their chest. If they follow these directions it is impossible to slow down and cause any issues.
There is no way that a cast member can control either of those two points, which is why I disagree with you that the Cast Member was at fault here.
