I hear what you're saying, but I think believing that what's currently happening is not precedent for what's next is pretty absurd. If the yea-sayers are right and the "GP" doesn't even notice a difference between a shuttle and a full circuit and they gleefully wait in the lines and/or pay to skip them completely unaware the concept of throughput, why ever build full circuit again? Like genuinely why? If even the big Statement Piece coasters aren't circuits, why does anything need to be? If it's almost always more "efficient" in terms of space, materials, and construction time to build a shuttle, and nobody looks at it any differently or is less likely to ride it because it is one, I really struggle to see the incentive for full-circuit rides at parks whose customers are having to get used to "boomerang coasters" the way customers at the "lesser" parks in the chain have had to in the past. fwiw the original boomerang does draw commentary everywhere I see it. A future full of shuttles is not one I like but it is one I expect
I can’t tell if you’re being sincere here or not, but you’ve either misunderstood the prevailing argument in defense of shuttles, or you’ve constructed a one doozy of a strawman. I don’t think anyone has said that the GP “doesn’t even notice a difference between a shuttle and a full circuits” in the sense that they literally can’t distinguish between the two. I’ve understood the pro-shuttle sentiment here to mean that the GP doesn’t necessarily consider shuttles worse than full-circuits.
That’s a massive distinction, because if the GP does view shuttle coasters as
a distinct type of coaster — just not inherently better or worse than any other type of coaster — then the obvious answer of why parks wouldn’t just start only building shuttles is because people want variety. I believe inverted coasters, dive coasters, wing coasters, wooden coasters, launch coasters, etc. are all
a distinct type of coaster in the GP’s mind and I don’t believe any one type is perceived as necessarily better or worse than any other type. I think shuttle coasters are viewed in the GP’s mind as “that kind of coaster that goes through the course forward then falls back through it again backwards” just as inverted coasters are viewed as “that kind of coaster where you hang below the track” or dive coasters are “that kind of coaster where you drop 90 degrees.”
The GP might like inverted coasters just as much as any other coaster, but if a park started building
only inverted coasters? Or only dive coasters? People would get tired of it and want something different. In a similar vein, people might not mind one “forwards then backwards” coaster or even two, but any more than that, and the novelty of that gimmick — like any other — wears off.
