From the comments here, I take it many don't ride coasters much if at all.
Uh, I have a season pass to Hersheypark...I not only ride rollercoasters, I am riding the super intense stuff on a regular basis. Also have been to a bunch of other parks with more on the bucket list. That's in addition to my hyperfixation about learning how they work.
It's not even that intense compared to roller coasters that exist elsewhere and that have been in existence for a while now. 62 mph max speed for Stardust Racers, max height of 133 feet Pantheon in Busch Gardens Williamsburg goes 78 MPH and is about 40 feet taller. You wanna talk intense? Skyrush at Hersheypark still is one of the most intense things I've ever experienced...and I am used to it. Storm Runner at Hersheypark is 20 years old, slightly taller than Stardust Racers, and goes from 0 to 72 MPH in two seconds. 90 degrees, straight up. Xcellerator at Knott's? 23 years old, over 200 ft, 82 mph (though I still think Storm Runner is somehow worse, having been on both).
Also, this creates g-forces, but below the max of what humans can tolerate. You know what actually creates more g-forces? Tighter inversions. Loops that are shaped like a circle instead of a teardrop (they don't make those because they figured out real fast, more than 100 years ago). Curves that don't have enough banking, hence why Wild Mouse rides can be super uncomfortable, and why Space Mountain had to be modified. Smaller, more compact inversions. A helix at high speeds (you know that turn at the bottom of Everest? Yeah, strong g forces right there).
A large rollercoaster like this? Sure, it's gonna have Gs, but nowhere near dangerous, and not nearly as many as some other rollercoasters have.
