Saying 99% of the general public hasn’t ridden an extreme spinner train is way more akin to saying 99% of the public hasn’t ridden in a Porsche 918 Spyder; they’re super rare, and even amongst the niche communities that know what they are they’re considered a worthwhile experience. Keep in mind, this is going to be the third extreme spinner in the world, and only the second in the US.
Edit because I realized there’s also currently fewer Extreme Spinners in the world than there are Arrow-Style 4D coasters. This is a big deal.
Then wouldn't magic mountain's thrill glider be a bigger deal by this logic
