It isn’t the most extreme rollercoaster in existence, like people seem to be implying. At a peak of 4 G’s, that’s in the median for a rollercoaster. Meaning, there’s nothing unusual about the G-forces of the X2 and nothing out of the ordinary was found about it. There are rollercoasters that go up to 6 G’s which aren’t causing people’s brains to explode.

Isn’t it more likely the deaths are coincidences? If 4 G’s was enough to cause fatal brain bleeds, then I’d assume stunt pilots, astronauts, and fighter pilots wouldn’t exist. And you can’t train your brain not to bleed.

What’s actually going on here? The ride was retired earlier today, as well, due to the pressure of the lawsuits: https://www.cbsnews.com/losangeles/news/six-flag-magic-mountain-x2-roller-coaster-closure/

I’m asking on Lemmy because when I tried to make an account and post on r/rollercoasters it got auto-modded, so fuck that.

    If 4 G’s was enough to cause fatal brain bleeds, then I’d assume stunt pilots, astronauts, and fighter pilots wouldn’t exist. And you can’t train your brain not to bleed.

    G forces are good for measuring sustained force in one direction, relevant when you’re worried about fluids draining somewhere. Pilots are trained not to make an inverted turn that would be 4Gs towards their head, because that drains too much blood into your brain and will cause a stroke. 4Gs towards your feet or back on the other hand is no problem. You can’t just have some G number and say that’s safe.

    NASA cancelled the Ares I rocket because even though the linear acceleration was less than 4Gs, it vibrated, and the astronauts all the way on one end of a 100 meter long vibrating stick would be getting jerked back and forth. Instead of excessive blood pressure popping a blood vessel, the threat was sloshing brain tissue stretching out and tearing blood vessels.

    Looking at some video of X2 it’s pretty obvious how people would get a brain bleed. It’s trying to rotate people while they go around the track, and the hydraulics visibly suck and are shuddering and jerking like crazy. If people’s legs are flopping around like limp noodles, their brain on the other end of that rotation is going to be sloshing and twisting and that’s eventually going to tear something in somebody. The ideal design of the coaster was probably safe but unlike a fixed track where it either breaks or it doesn’t some 4D hydraulic system requires a lot of money to keep it ideal.

    It’s not the maximum G force being experienced that is causing the issue. If that was the case, all jet fighter pilots would be brain damaged.

    I’m pretty sure it must be sudden changes in direction sloshing the brain around inside the cranium.

      Yeah thats the issue with this ride. When i looked at them they all say its a very rough ride and your head is thrown into the sides several times throughout which may not be a huge issue for a lot of people, but for it to be bad enough to even do this to a few people now and again is kind of terrifying. They gotta fix it, im not even sure why thats up for discussion.

      When you look at it from a scientific perspective, 4 G is average for a rollercoaster. And 4 G’s is not even close to being powerful enough to tear people’s brains apart. To say I’m skeptical these lawsuits are being 100% truthful would be an understatement. I’ve ridden the X2 plenty of times.

        Please explain what part of “two deaths is a coincidence, three or more deaths is a pattern” you don’t understand.

      Brain injuries from what? It’s been established that 4 G’s can’t cause brain-bleeds. 4 G’s is average for a rollercoaster. Some even go up to 6 yet these 6 G rollercoasters aren’t causing brain-bleeds.

      Keyword here is “allege”.

        there’s nothing unusual about the G-forces of the X2

        So this is disingenuous, the whipping motions that the riders experience on the x2 are much different than the higher g shockwave https://rollercoaster.fandom.com/wiki/Shock_Wave_(Six_Flags_Over_Texas)

        You can see the way the track is designed, the riders are pushed down and back into the seats with a gradual increase in force on the highest g loop.

        I’d agree with you that 4gs isn’t enough to harm a healthy adult, but the attraction has a responsibility to provide an accurate presentation of the risk and should account for riders that unknowingly are at risk. If they aren’t accounting for riders that have an invisible abnormality, they shouldn’t operate the ride.

        There’s no marketing material on these rides that say “only ride if you do not have any abnormal cardiovascular physiology” and if they did I’d wonder what kind of screening they expect their riders to pass.

          You don’t have to study neuroscience to realize that higher G rollercoasters aren’t tearing people’s brains open and 4 G’s is merely average for a rollercoaster.
