Remember the mechanic from Seinfeld?
If you’re working on a new product, there’s a good chance that—like the mechanic—you’re far more obsessed with your product than your customers are.
You may obsess over every detail. Your customers might not.
If you find most of your target demographic shrugging their shoulders, it’s worth considering whether you actually empathize with them, or if you just think you do. To you, the problem you’re solving is hugely important. But, too often, it’s trivial to your target users. They may care about something else entirely.
To them, the washer fluid is fine.
