Yeah, I know this board loves to try to spin a web of made-up justification for a quirk or flaw in the game in the process of discounting a complaint, but I don't buy it. It's not there to teach you a parable about life and waiting. It's there because the loading process is artificially hard scripted to play out one step at a time, yielding an inorganic and nonsensical result, both visually and mechanically. In the real world unless there's some specific technical or safety reason, seats start to be filled the moment they're empty. There's a reason exits and entrances are so often on opposite sides of the platform. So it certainly doesn't happen the way it does because it's more realistic. Waiting is what happens in queues. The platform is a high-volume processing station, people standing around with cars waiting there means something's gone wrong.
It's time to get out of the habit of responding to a complaint by saying "here's how you ignore it, or change your viewpoint of it entirely to be mine." Not every complaint needs to be responded to with gaslighting or diversionary "actually...."s. Let them live and breathe. The game will survive negative feedback, it's a big boy.
As to the economy thing, which is an actual point, I don't think it needs to be relevant to this situation. They're two separate issues, and the loading speeds are not the core reason the economy is so easy or ineffective as a game mechanic. Price-response behavior on rides can be easily tweaked to adjust for higher throughput speeds if necessary.
*edit* I should also say my feelings about the loading process have nothing to do with their relation to real life times. I get the point trying to be made by the Super Official calculations about how loading times match up to real world times now, but we're talking about an in-game universe where it takes guests a week to walk across a large park, so that particular relationship is pretty irrelevant I think lol.
