I've noticed this trend for a while now, since before vehicles were released. People can't seem to wrap their noodle around the fact that what's presented in Mondoids is not final and there's still work to be done/room for improvement, even if its written directly in the Mondoid.
The problem is people get so used to what's in Zomboid already that when something changes (animations for example) it's going to look weird to people regardless, because it's not what they're familiar with. If the new animations were in from the start, people wouldn't bat an eyelid.
Keep doing what you're doing though. We all appreciate it massively and are super excited for the update.
The idea to have the tutorial as a toggle is definitely a good one. Too often I leave it selected by mistake when trying to go into Survival. Then there's the occasional critique that Survival looks more like a heading in its current position than a button, others have brought up.
