When I used to operate rides if a guest complained about anything we needed to do something, we would not just forget about it. If it was car related we wouldn't load the car until the correct person could check it out, if it was a brake problem we would watch and see if it braked to hard to little etc. It also helps that were I worked there are cameras at every angle of the ride and could actually see a branch on a track and hopefully stop it on the lift or block before it's to late. Six flags does need to improve having their operators have a full complete view of the ride through cameras of some sort.
