It’s widely understood and documented that carousels are a bad idea, and plenty has been written about it.
(I should clarify that the problems are with carousels as a way of presenting diverse widgets; as a way of presenting a collection of pictures about a single item, it can be acceptable.)
If your goal is user friendliness, it would behoove you to use a design which is user friendly.
Using a design which is user unfriendly and asking "how can I make this unfriendly design seem friendly" seems to be approaching the problem from the wrong direction: the design choice itself is the biggest contributor to user friendliness.
Either you care more about yourself and your design choices than user friendliness, or vice versa, and both are totally valid options, but don't pick the former and claim the latter.
Smooth scrolling is a great example. The native API allows a user to interrupt at any point. Most JS implementations are janky as all hell and users suffer.
Scold design choices all you like but don’t expect to be listened to. Especially when you’re not providing any actual reasons why “carousels are still a bad idea”.
