^True, you can't expect someone who isn't an enthusiast to be familiar with ride names, stats, and workings, but sometimes a person makes a comment which leaves you no choice but to believe that they are too dense to be aware of the world around them. There's a topic like this over at TPR with over a hundred pages that I looked at once. Take a look and you'll see what I mean.
The stupidest thing I've heard was that the nets after the station on Montu are there to catch you if you fall out so that the crocodiles won't eat you. This makes no sense because the net is obviously not mean to bear the weight of a person, it would take a miracle for someone to fall out of a seat leaning back on a flat bit of track by accident even if the restraints failed, and no company would operate a ride with the kind of hazards supposedly present.
Honorable mention goes to the widely-held belief that trains commonly get stuck in loops when the power goes out. This shouldn't make sense, even to a non-enthusiasts. Gravity powered coasters have no running rails, so unless the entire structure is carrying a charge, it's not electrically powered. Second, if it was powered, why would there need to be a chain lift (again, clearly visible). And if we are to assume that the train would immediately stop when the power cuts off, then the power would have been responsible for every bit of momentum at any point of the ride. If that was the case, why would the lift hill be so slow, when the rest of the ride is fast? Why would there be a lift hill in the first place? All that aside, if the coaster "lost power" , why would it come to an instantaneous halt? It would still be carried forward by momentum even if its source of locomotion was cut off at the top of the loop. And even if the train came to an instant stop, what are the odds that it would be perfectly balanced at the top of the loop (with cobra rolls and batwings its a different story, I'll admit)? There's just no logic behind this idea.
