I agree. From what I read on the UO AP page, it sounds like team members don't like asking guests to do this, and they try to ask in a non-direct way - for example, asking them if they have been on this ride before. They would rather not ask. But if/when they respectfully ask guests to sit in the test seats, it helps to avoid a possible situation later at load. It would be uncomfortable for a guest to get all the way to load and have difficulty getting into the ride vehicle. Then ride operations have be paused and whatnot, as you mentioned.
