Tell me about a time you disagreed with a product or design decision. How did you handle it?

Imagine you and a friend are planning a road trip. You want to take the scenic route because it's beautiful, but your friend insists on the highway because it's faster. You both want the trip to be great, but you disagree on how to get there. This question is about how you handle that kind of disagreement at work—when you think a product or design choice is wrong, and you need to convince others without burning bridges.
